Summary:
Push webhook events to redis queue with key based on docId.
Remove events from redis after sending using LTRIM.
Put failed events back on the end of the queue under normal circumstances.
When the event queue gets too long:
- Wait until it gets consumed before continuing.
- Drop failed events (i.e. don't put them back on the end of the queue)
- Limit webhook retries to 5
Test Plan: Tested that interactions with redis are as expected using redis MONITOR command.

The document collecting new user info
(https://docs.getgrist.com/doc/GristNewUserInfo) got very slow, taking 40+
seconds for cold open. Sign-up submissions had to wait this time to proceed to
next step, because they waited for the write to this doc, which was blocked on
the Calculate action to complete.
Two changes were made: one to remove all expensive columns and summaries in the
actual doc, so the doc is back to opening in single seconds, and times should
be acceptable now.
The second change is this diff: to avoid waiting for the write step, so that it
doesn't affect users even if it gets slow again.
Test Plan: Existing test continues to work with a minor reliability tweak.

Summary:
This verifies that all existing tests are capable of running under python3/gvisor, and fixes the small issues that came up. It does not yet activate python3 tests on all diffs, only diffs that specifically request them.
* Adds a suffix in test names and output directories for tests run with PYTHON_VERSION=3, so that results of the same test run with and without the flag can be aggregated cleanly.
* Adds support for checkpointing to the gvisor sandbox adapter.
* Prepares a checkpoint made after grist python code has loaded in the gvisor sandbox.
* Changes how `DOC_URL` is passed to the sandbox, since it can no longer be passed in as an environment variable when using checkpoints.
* Uses the checkpoint to speed up tests using the gvisor sandbox, otherwise a lot of tests need more time (especially on mac under docker).
* Directs jenkins to run all tests with python2 and python3 when a new file `buildtools/changelogs/python.txt` is touched (this diff counts as touching that file).
* Tweaks miscellaneous tests
- some needed fixes exposed by slightly different timing
- a small number actually give different results in py3 (removal of `u` prefixes).
- some needed a little more time
The DOC_URL change is not the ultimate solution we want for DOC_URL. Eventually it should be a variable that gets updated, like the date perhaps. This is just a small pragmatic change to preserve existing behavior.
Tests are run mindlessly as py3, and for some tests it won't change anything (e.g. if they do not use NSandbox). Tests are not run in parallel, doubling overall test time.
Checkpoints could be useful in deployment, though this diff doesn't use them there.
The application of checkpoints doesn't check for other configuration like 3-versus-5-pipe that we don't actually use.
Python2 tests run using pynbox as always for now.
The diff got sufficiently bulky that I didn't tackle running py3 on "regular" diffs in it. My preference, given that most tests don't appear to stress the python side of things, would be to make a selection of the tests that do and a few wild cards, and run those tests on both pythons rather then all of them. For diffs making a significant python change, I'd propose touching buildtools/changelogs/python.txt for full tests. But this is a conversation in progress.
A total of 6886 tests ran on this diff.
Test Plan: this is a step in preparing tests for py3 transition

- Puts events on a queue in memory and ensures they are sent in the order they were generated.
- Makes the caller (Sharing.ts) wait until changed records have been fetched from the DB, but allows it to continue after while remaining work happens asynchronously.
- Gathers all new webhook events into an array so they can be backed up to the queue on redis in a single command (in a future diff).
- Uses changes in isReady to determine event type, no more 'existed before'
The structure of the code has changed a lot, so I think the scope of the diff needs to stop here. Lots of work is still deferred in TODOs.

Once the data engine starts, it will run a calculation and send any updates made. Changes to the document will be blocked until the engine is started and the initial calculation is complete.
The increase in responsiveness is useful in its own right, and also reduces the impact of an extra startup time in a candidate next-generation sandbox.

This removes the need for any information drawn from the content of recent actions when loading a document.
The undo/redo system does need some facts about recent actions up front. But that system has an important restriction: only actions a particular client is known to have generated can be undone by that client.
So in this diff, as we store which client has performed an action, we also store the few pieces of metadata about that action that the undo/redo system needs: `linkId`, `otherId`, `rowIdHint`, `isUndo` fields. These are all small integers (or in one case a boolean).
An existing limitation is that information about which client has performed which action is stored in memory in the worker, and not persisted anywhere. This diff does not change that limitation, meaning that undos continue to not survive a worker transition. A reasonable way to deal with that would be to back the store with redis.

- New DB entity Secret to hold the webhook URL and unsubscribe key
- New document metatable _grist_Triggers subscribes to table changes and points to a secret to use for a webhook
- New file Triggers.ts processes action summaries and uses the two new tables to send webhooks.
- Also went on a bit of a diversion and made a typesafe subclass of TableData for metatables.
I think this is essentially good enough for a first diff, to keep the diffs manageable and to talk about the overall structure. Future diffs can add tests and more robustness using redis etc. After this diff I can also start building the Zapier integration privately.

This changes the default behavior of grist-core to now start off in
anonymous mode, with an explicit sign-in step available. If SAML is not configured,
the sign-in operation will unconditionally sign the user in as a default
user, without any password check or other security. The user email is
taken from GRIST_DEFAULT_EMAIL if set. This is a significant change, but

Then when converting back in `convertQueryFromRefs` we construct `Query.contains: {[colId: string]: boolean}`.
Finally `getFilterFunc` uses `Query.contains` to decide what kind of filtering to do.
This is not pretty, but the existing code is already very complex and it was hard to find something that wouldn't require touching loads of code just to make things compile.
