rPe0a8cac703d1: When no master database is configured, automatically degrade to read-only mode
Summary

Ref T4571. If cluster.databases is configured but only has replicas, implicitly drop to read-only mode and send writes to a replica.

Test Plan
  • Disabled the master, saw Phabricator automatically degrade into read-only mode against replicas.
  • (Also tested: explicit read-only mode, non-cluster mode, properly configured cluster mode).
