epriestley 2447d9bdf2 Begin improving modularity of IndexEngine, add locks
Summary:
Ref T9890. Ref T9979. Several adjacent goals:

  - The `SearchEngine` vs `ApplicationSearchEngine` thing is really confusing. There are also a bunch of confusing class names and class relationships within the fulltext indexing. I want to rename these classes to be more standard (`IndexEngine`, `IndexEngineExtension`, etc). Rename `SearchIndexer` to `IndexEngine`. A future change will rename `SearchEngine`.
  - Add the index locks described in T9890.
  - Structure things a little more normally so future diffs can do the "EngineExtension" thing more cleanly.

Test Plan:
Indexing:

  - Renamed a task to have a unique word in the title.
  - Ran `bin/search index Txxx`.
  - Searched for unique word.
  - Found task.

Locking:

  - Added a `sleep(10)` after the `lock()` call.
  - Ran `bin/search index Txxx` in two windows.
  - Saw first one lock, sleep 10 seconds, index.
  - Saw second one give up temporarily after failing to grab the lock.
