Maintenance mode blocks non-GET HTTP requests

Problem to solve

We want to add a read-only maintenance mode so sysadmins can block writes. In particular, this allows Geo to finish replicating all data before planned failovers.

Proposal

The application setting maintenance_mode_enabled should already exist.

• Block non-GET HTTP requests when maintenance_mode_enabled is enabled
