rP3c26e384872a: Provide a simple read-only maintenance mode for repositories
Summary

Ref T13393. While doing a shard migration in the Phacility cluster, we'd like to stop writes to the migrating repository. It's safe to continue serving reads.

Add a simple maintenance mode for making repositories completely read-only during maintenance.

Test Plan

Put a repository into read-only mode, tried to write via HTTP + SSH. Viewed web UI. Took it back out of maintenance mode.
