Summary:
Adds a new endpoint to update webhook.
Perform some refactoring to allow code reuse from endpoint allowing to _subscribe and _unsubscribe webhooks.
One aspect of webhook is that url are stored in the home db while the rest of the fields (tableRef, isReadyColRef, ...) are stored in sqlite. So care must be taken when updating fields, to properly rollback if anything should fail.
Follow up diff will bring UI to edit webhook list

for users who don't automatically have deep rights
to the document, provide them with attachment metadata only
for rows they have access to. This is a little tricky to
do efficiently. We provide attachment metadata when an
individual table is fetched, rather than on initial document
load, so we don't block that load on a full document scan.
We provide attachment metadata to a client when we see that
we are shipping rows mentioning particular attachments,
without making any effort to keep track of the metadata they
already have.

Summary:
- New /webhooks event that lists all webhooks in a document (available for owners),
- Monitoring webhooks usage and saving it in memory or Redis,
- Loosening _usubscribe API endpoint, so that the information returned from the /webhook endpoint is enough to unsubscribe,
- Owners can remove webhook without the unsubscribe key.
The endpoint lists all webhooks that are registered in a document, not just webhooks from a single table.
There are two status fields. First for the webhook, second for the last request attempt.
Webhook can have 5 statuses: 'idle', 'sending', 'retrying', 'postponed', 'error', which roughly describes what the
sendLoop is currently doing. The 'error' status describes a situation when all request attempts failed and the queue needs
to be drained, so some requests were dropped.
The last request status can only be: 'success', 'failure' or 'rejected'. Rejected means that the last batch was dropped because the
queue was too long.

Summary:
This diff adds a new `BulkAddOrUpdateRecord` user action which is what is sounds like:
- A bulk version of the existing `AddOrUpdateRecord` action.
- Much more efficient for operating on many records than applying many individual actions.
- Column values are specified as maps from `colId` to arrays of values as usual.
- Produces bulk versions of `AddRecord` and `UpdateRecord` actions instead of many individual actions.
Examples of users wanting to use something like `AddOrUpdateRecord` with large numbers of records:
- https://grist.slack.com/archives/C0234CPPXPA/p1651789710290879

- https://grist.slack.com/archives/C0234CPPXPA/p1663069291726159
I tested what made many `AddOrUpdateRecord` actions slow in the first place. It was almost entirely due to producing many individual `AddRecord` user actions. About half of that time was for processing the resulting `AddRecord` doc actions. Lookups and updates were not a problem. With these changes, the slowness is gone.
The Python user action implementation is more complex but there are no surprises. The JS API now groups `records` based on the keys of `require` and `fields` so that `BulkAddOrUpdateRecord` can be applied to each group.
Test Plan: Update and extend Python and DocApi tests.

Summary: This particular test fails often enough to be annoying but not often enough to be worrying. It's not clear why, but it seems like a race condition involving redis. Fixing the test 'properly' seems hard and not worth the effort. Looking at the past 20 Jenkins builds, I found this test failing once. If we assume that the probability of failing is 1/20 (it's probably less since the test actually runs 3 times with different server configurations) then the probability of failing 3 times independently is (1/20)^3 = 1/8000, so `this.retry(3)` seems like a good enough solution. See also: https://grist.slack.com/archives/C0234CPPXPA/p1652909955773049
Test Plan: Manually made the test fail randomly 90% of the time, in which case `this.retries(3)` was not usually enough to prevent failures, but `this.retries(300)` was.

Summary:
This adds rudimentary support for opening certain SQLite files in Grist.
If you have a file such as `landing.db` in Grist, you can convert it to Grist format by doing (either in monorepo or grist-core):
```
yarn run cli -h
yarn run cli sqlite -h
yarn run cli sqlite gristify landing.db
```
The file is now openable by Grist. To actually do so with the regular Grist server, you'll need to either import it, or convert some doc you don't care about in the `samples/` directory to be a soft link to it (and then force a reload).
This implementation is a rudimentary experiment. Here are some awkwardnesses:
* Only tables that happen to have a column called `id`, and where the column happens to be an integer, can be opened directly with Grist as it is today. That could be generalized, but it looked more than a Gristathon's worth of work, so I instead used SQLite views.
* Grist will handle tables that start with an uncapitalized letter a bit erratically. You can successfully add columns, for example, but removing them will cause sadness - Grist will rename the table in a confused way.
* I didn't attempt to deal with column names with spaces etc (though views could deal with those).
* I haven't tried to do any fancy type mapping.
* Columns with constraints can make adding new rows impossible in Grist, since Grist requires that a row can be added with just a single cell set.

Summary:
When a user requests to read the contents of an attachment, only allow the request if there exists a cell in an attachment column that contains the attachment and which they have read access to.
This does not cover:
* Granular write access for attachments. In particular, a user who can write to any attachment column should be considered to have full read access to all attachment columns, currently.
* Access control of attachment metadata such as name and format.
The implementation uses a sql query that requires a scan, and some notes on how this could be optimized in future. The web client was updated to specify the cell to check for access, and performance seemed fine in casual testing on a doc with 1000s of attachments. I'm not sure how performance would hold up as the set of access rules grows as well.

Building:
- Builds no longer wait for tsc for either client, server, or test targets. All use esbuild which is very fast.
- Build still runs tsc, but only to report errors. This may be turned off with `SKIP_TSC=1` env var.
- Grist-core continues to build using tsc.
- Esbuild requires ES6 module semantics. Typescript's esModuleInterop is turned
on, so that tsc accepts and enforces correct usage.
- Client-side code is watched and bundled by webpack as before (using esbuild-loader)
Code changes:
- Imports must now follow ES6 semantics: `import * as X from ...` produces a
module object; to import functions or class instances, use `import X from ...`.
- Everything is now built with isolatedModules flag. Some exports were updated for it.
Packages:
- Upgraded browserify dependency, and related packages (used for the distribution-building step).
- Building the distribution now uses esbuild's minification. babel-minify is no longer used.
Test Plan: Should have no behavior changes, existing tests should pass, and docker image should build too.

- Add a needReload flag in clientConnect for a clear indication whent the

avoid logging sessionId)
Note that despite the big refactoring, this only addresses a fairly rare
situation, with websocket failures while server is trying to send to the
client. It includes no improvements for failures while the client is sending to
the server.
(I looked for an existing library that would take care of these issues. A relevant article I found is https://docs.microsoft.com/en-us/azure/azure-web-pubsub/howto-develop-reliable-clients, but it doesn't include a library for both ends, and is still in review.

For self-hosted Grist, forward auth has proven useful, where
some proxy wrapped around Grist manages authentication, and

The current implementation is adequate when Grist is the
only place where the user logs in or out, but is confusing
otherwise (see https://github.com/gristlabs/grist-core/issues/207).
Here we take some steps to broaden the scenarios Grist's
forward auth support can be used with:
* When a trusted header is present and is blank, treat
that as the user not being logged in, and don't look
any further for identity information. Specifically,
don't look in Grist's session information.
* Add a `GRIST_IGNORE_SESSION` flag to entirely prevent
Grist from picking up identity information from a cookie,
in order to avoid confusion between multiple login methods.
* Add tests for common scenarios.
