Remove the ability to customize the postgres_data_dir (#1798)

* in the sclorg Postgresql 15 image, the PGDATA directory is hardcoded
* if users were to modify this directory, they would only change the
  directory the pvc is mounted to, not the directory PostgreSQL uses.
  This would result in loss of data.
* switch from /var/lib/pgsql/data/pgdata to /var/lib/pgsql/data/userdata

 **Note**: If `postgres_storage_class` is not defined, PostgreSQL will store it's data on a volume using the default storage class for your cluster.
+
+#### Note about overriding the postgres image
+
+We recommend you use the default image sclorg image. If you are coming from a deployment using the old postgres image from dockerhub (postgres:13), upgrading from awx-operator version 2.12.2 and below to 2.15.0+ will handle migrating your data to the new postgresql image (postgresql-15-c9s).
+
+You can no longer configure a custom `postgres_data_path` because it is hardcoded in the quay.io/sclorg/postgresql-15-c9s image.
+
+If you override the postgres image to use a custom postgres image like postgres:15 for example, the default data directory path may be different. These images cannot be used interchangeably.
