Summary:
This commit removes ChatLog entirely. All of the application files are removed, and the migrations used are stubbed out. I stubbed the migrations as that allows for existing installs to make no changes, but new installs will not create the database.
Fixes T15126
Test Plan: Loaded up http://phorge.local/chatlog and confirmed the 404. Loaded up http://phorge.local/applications/view/PhabricatorChatLogApplication and confirmed the 404. Created a new database prefix and ran `bin/storage upgrade` against it, confirmed that the chatlog database was not created. Restored another prefix (an old one) and ran `bin/storage upgrade` and confirmed database was not deleted.

Summary:
This diff adds conduit methods for searching for legalpad documents and signatures. This is very helpful for auditing who's actually signed a document. It also fixes the "contributorPHIDs" constraint in the existing search engine.
In order to expose legalpad signatures through Conduit, this adds a `phid` column to the `legalpad_documentsignature` table. It includes a migration (in the style of many previous phid-adding migrations) to actually populate the column.
Test Plan: We run this on my company's internal fork and it seems to work okay. I don't think any other conduit methods anywhere have tests (???), but if you can point me at one I'm glad to write a unit test!

Summary:
Ref T13591. Worker queue tasks which affect commits currently (mostly) store the commit as an "objectPHID", but do not directly reference the repository the commit belongs to.
This can make certain operations (like "change the priority of all tasks affecting repository Y") more difficult than it needs to be.
Support a "containerPHID", similar to the field of the same name on builds, that can store a parent object like a repository and better support operations against subsets of tasks.
See also D11044 for the genesis of "objectPHID".
This depends on the introduction of storage patch phases (in D21529) so that earlier migrations which queue worker tasks don't try to insert this column before it actually exists.

Summary:
Ref T13591. Some storage patches queue worker tasks, currently always to rebuild search indexes.
These patches can not execute in creation order if a later patch modifies the worker task table, since they'll try to perform a modern INSERT against an out-of-date table schema. Such a modification is desirable in the context of T13591, but making it causes these patches to fail.
Patches have an existing "after" mechanism which allows them to have explicit dependencies. This mechanism could be used to resolve this issue, but all patches with a dependency like this would need to be updated every time the queue table changes.
Instead, introduce "phases" to provide broader ordering rules. There are now two phases: "default" and "worker". Patches in the "worker" phase execute after patches in the "default" phase.
Phases may eventually be further separated, but

- Ran `bin/storage status`, saw patches annotated with phases.

Summary:
See <https://discourse.phabricator-community.org/t/storage-upgrade-error/3748>.
It is broadly unsafe for migrations to use "save()". If the object gains new fields later, the query will include "SET newField = X", which will fail against the old schema which is in the process of being upgraded.
Instead, migrations must issue raw SQL against the schema as it is expected to exist at the time the migration executes.
Migrations have followed this rule for a long time, but this ~6 year old migration was overlooked. Update it to issue a raw query to perform the policy update.
Test Plan: This is somewhat flimsy since rebuilding a genuine reproduction case is messy, but used "bin/storage --apply ..." to at least get the new query to execute against modern Phabricator without issues.
