James Brown a4948ec800 Add conduit endpoints for querying legalpad
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!
