postgresql: don't attempt to start the DB before we setup the DB

When we boot the first time the postgresql service will [FAIL] and
the following error is reported:

pg_ctl[288]: pg_ctl: directory "/etc/postgresql/data" does not exist

This is a result of the service being started before a call to
postgresql's initdb is made on the PGDATA directory, usually made by
the package's default 'postgresql-setup' or our 'postgresql-init'
scripts.

We split our 'postgresql-init' script into two, the first part which
does the 'initdb' can be executed as part of the postgresql.service
'ExecStartPre' allowing the postgresql.service to not fail. The
remainder of 'postgresql-init' script is executed as before, via the
postgresql-init.service on first boot.

This change also fixes some of the first boot startup races that was
preventing some of the openstack '*-init' services which do DB
configuration for openstack components from executing correctly.
