fbae81648c (core) Add options to /status health-check endpoints to check DB and Redis liveness.
Summary:
- /status accepts new optional query parameters: db=1, redis=1, and timeout=<ms> (defaults to 10_000).
- These verify that the server can make trivial calls to DB/Redis, and that they return within the timeout.
- New HealthCheck tests simulates DB and Redis problems.
- Added resilience to Redis reconnects (helped by a test case that simulates disconnects)
- When closing Redis-based session store, disconnect from Redis (to avoid hanging tests)

Some associated test reorg:
- Move stripeTools out of test/nbrowser, and remove an unnecessary dependency,
  to avoid starting up browser for gen-server tests.
- Move TcpForwarder to its own file, to use in the new test.

Test Plan: Added a new HealthCheck test that simulates DB and Redis problems.

51ff72c15e (core) Faster builds all around.
Summary:
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.

ff77ecc6c6 (core) deal with SQLITE_BUSY: database is locked during tests
Summary:
During testing, and in some dev configurations, we make connections to
the Grist home database from multiple processes, and store it in Sqlite.
This is a situation prone to file locks in Sqlite. We set a busy_timeout
parameter to help, but transactions may still fail immediately. This
diff adds retries to our patch of TypeORM for Sqlite transactions
(which without the patch are already flakey for other reasons
https://github.com/typeorm/typeorm/issues/1884#issuecomment-380767213).

Without this change, I can tickly SQLITE_BUSY problems fairly
reliably with the DocApi tests. With this change, I can't so far.

This change should not affect deployments of our SaaS (which use
Postgres for home db) or grist-core/grist-ee (which access home
db from a single process in default configuration).

Test Plan: repeated running of DocApi tests

dcaa2b4f29 (core) move DocUsageBanner to ext
Summary:
grist-ee build was failing since it didn't have a
DocUsageBanner implementation available. Made the implementation
added to monorepo available, since it will be useful to improve
the activation banner.

71519d9e5c (core) revamp snapshot inventory
Summary:
Deliberate changes:
 * save snapshots to s3 prior to migrations.
 * label migration snapshots in s3 metadata.
 * avoid pruning migration snapshots for a month.

Opportunistic changes:
 * Associate document timezone with snapshots, so pruning can respect timezones.
 * Associate actionHash/Num with snapshots.
 * Record time of last change in snapshots (rather than just s3 upload time, which could be a while later).

This ended up being a biggish change, because there was nowhere ideal to put tags (list of possibilities in diff).

Test Plan: added tests

5ef889addd (core) move home server into core
Summary: This moves enough server material into core to run a home server.  The data engine is not yet incorporated (though in manual testing it works when ported).

Test Plan: existing tests pass
