epriestley 29a3cd5121 Add "Manual Activities", to tell administrators to rebuild the search index
Summary:
Ref T11922. After updating to HEAD of `master`, you need to manually rebuild the index. We don't do this during `bin/storage upgrade` because it can take a very long time (`secure.phabricator.com` took roughly an hour) and can happen while Phabricator is running.

However, if we don't warn users about this they'll just get a broken index unless they go read the changelog (or file an issue, then we tell them to go read the changelog).

This adds a very simple table for notes to administrators so we can write a "you need to go rebuild the index" note, then adds one.

Administrators clear the note by completing the activity and running `bin/config done reindex`. This isn't automatic because there are various strategies you can use to approach the issue, which I'll discuss in greater detail in the linked documentation.

Also, fix an issue where `bin/storage upgrade --apply <patch>` could try to re-mark an already-applied patch as applied.

Test Plan:
  - Ran storage ugrades.
  - Got instructions to rebuild search index.
  - Cleared instructions with `bin/config done reindex`.
