Geo: Improve HA install docs

Michael Kozono requested to merge mk/improve-geo-ha-docs into master

What does this MR do?

Improves Geo HA docs.

  • Adds caveat that we don't support PG HA in secondaries
  • Suggest ensuring the secondary cluster works without Geo first
  • Adds configuration to disable geo_logcursor on the PG read-replica node to prevent it from attempting to configure Rails if you don't have any Rails services explicitly enabled. Otherwise, reconfigure could get blocked on things like erroring on migrating databases even though you never asked to run geo_logcursor on the PG node.
  • Adds suggestion to run backend Rails services on backend application nodes
