Paul Fitzpatrick	438f259687	(core) start reconciling forking with granular access ... Summary: This allows a fork to be made by a user if: * That user is an owner of the document being forked, or * That user has full read access to the document being forked. The bulk of the diff is reorganization of how forking is done. ActiveDoc.fork is now responsible for creating a fork, not just a docId/urlId for the fork. Since fork creation should not be limited to the doc worker hosting the trunk, a helper endpoint is added for placing the fork. The change required sanitizing worker allocation a bit, and allowed session knowledge to be removed from HostedStorageManager. Test Plan: Added test; existing tests pass.

Paul Fitzpatrick	d6ff1361cb	(core) support GRIST_WORKER_GROUP to place worker into an exclusive group ... Summary: In an emergency, we may want to serve certain documents with "old" workers as we fix problems. This diff adds some support for that. * Creates duplicate task definitions and services for staging and production doc workers (called grist-docs-staging2 and grist-docs-prod2), pulling from distinct docker tags (staging2 and prod2). The services are set to have zero workers until we need them. * These new workers are started with a new env variable `GRIST_WORKER_GROUP` set to `secondary`. * The `GRIST_WORKER_GROUP` variable, if set, makes the worker available to documents in the named group, and only that group. * An unauthenticated `/assign` endpoint is added to documents which, when POSTed to, checks that the doc is served by a worker in the desired group for that doc (as set manually in redis), and if not frees the doc up for reassignment. This makes it possible to move individual docs between workers without redeployments. The bash scripts added are a record of how the task definitions + services were created. The services could just have been copied manually, but the task definitions will need to be updated whenever the definitions for the main doc workers are updated, so it is worth scripting that. For example, if a certain document were to fail on a new deployment of Grist, but rolling back the full deployment wasn't practical: * Set prod2 tag in docker to desired codebase for that document * Set desired_count for grist-docs-prod2 service to non-zero * Set doc-<docid>-group for that doc in redis to secondary * Hit /api/docs/<docid>/assign to move the doc to grist-docs-prod2 (If the document needs to be reverted to a previous snapshot, that currently would need doing manually - could be made simpler, but not in scope of this diff).

Paul Fitzpatrick	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).

Paul Fitzpatrick	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).
