Docs: update Consul nodes docs
Follow up from !3645 (comment 50909359):
@dblessing I'm organizing the admin index for #4258 (closed) and noticed that there's this file:
consul.mdunlinked from the higher-level doc (https://docs.gitlab.com/ee/administration/high_availability/).
Since you're already working on this, could you please mention it and link it from
database.md? Also, the consul nodes would fall into "active/active" or "active/passive" infrastructure? Can you please mention/link the consul.md file from https://docs.gitlab.com/ee/administration/high_availability/README.html?
@marcia It's interesting that the separate Consul page exists. I'm going to leave that unlinked for now and not make any changes with regard to Consul in this MR. I think we need to decide if we want a dedicated Consul page or if it should be embedded in the database page and make those changes accordingly. At the moment it's a big fragmented if we also link this Consul page you found.
What to do
- Figure out if we want this Consul doc apart
- Crosslink it with database.md
- Figure out how to link it from https://docs.gitlab.com/ee/administration/high_availability/README.html
