Add support for PostgreSQL 11.X to gitlab-ctl pg-upgrade for single database nodes
The package should install PostgreSQL 10 by default. But, running gitlab-ctl pg-upgrade
manually should upgrade the database to the bundled PostgreSQL 11.
This should work on single node installations, and installations using a separate database node with the omnibus-gitlab provided PostgreSQL. We will handle GEO and PG HA installations in separate issues.
We'll need to be able to upgrade from 9.6.X or 10.X. The upgrade path will depend on the results of #4972 (closed)
Blocked by #4972 (closed)
