- use awx-python in shebang in dev env
- scl enable where needed for rhel7 & container installs
- use scram-sha-256 pg user hashing by default
- ensure psycopg2 is using the correct PG_CONFIG at build time for the right libpq version
`oc new-app --template=postgresql-persistent` has been kind of a pain. It would attempt to create a Persistent Volume, but does not allow you to specify the storageClass.
This code assumes that a Persistent Volume is already available and will fail with a helpful error message if it is not.
