Summary: Fixes T6395. Ref T6350. I guess I missed this code spot in prior testing / I definitely didn't run an empty commit through it. Works now though.

Test Plan: made an empty commit and observed stuck importing status and errors in phd log. applied patch and commit successfully imported with no errors. made another empty commit and it imported as well

MetaMTA - make test mail implementation support message id headers by default

Summary: Fixes T6372. Apparently ye olde error logs get some crazy spam action as is... Looking around at call sites, we do not specify $config (which could specify the supportage of message id header) so it seems correct to default this to something. I went with "true" as the spot we use this seems like pretty easy stuff that will always work.

Test Plan: lots of thinking

Allow standard custom fields to be indexed in global fulltext search

Summary: Fixes T6399. This allows you to use global search to find projects by searching for text in their descriptions.

Add AlmanacBinding, to bind a service to an interface

Summary: Ref T5833. Allows you to bind a service (like `db.example.com`) to one or more interfaces (for example, to specify a pool with one read/write host and two read-only hosts). You can't configure which hosts have which properties yet, but you can add all the relevant interfaces to the service. Next diff will start supporting service, binding, and device properties like "is writable", "is active", etc., so that Almanac will be able to express operations like "change which database is writable", "disable writes", "bring a device down", etc.

Test Plan: See screenshots.
