Merge branch 'ha_docs_auto_migrate_false' into 'master'

Browse source 
Add `gitlab_rails['auto_migrate'] = false` to HA docs for Redis/PG [ci skip]

## What does this MR do?

In a high availability configuration, the Redis and PostgreSQL nodes
should not attempt to run database migrations. In fact, trying will
result in errors about not providing a database password. To
prevent errors and confusion, add this configurtion to these nodes'
`gitlab.rb` file.
