Previously, I thought it was better to drop the site into reading mode
when Redis has failed over to the replica but it created more errors
while Redis is in readonly mode since ActiveRecord would prevent us from
writing to PG even though PG is up.

DEV: Enable readonly mode for all multisite sites when PG goes down.

The risk here is that the database for one site goes down in the multisite setup and we drop everything to readonly mode. However, I discussed this with Sam and we agree that one database having problem is very rare. Most of the time, it is the entire DB cluster that goes down.
