Let migrate to the new openstacklib::db::postgresql helper for
postgresql backend. This commit also unpin postgresql fixture
(openstacklib support now the latest version of postgre module).
Change-Id: Ibcc206b4e5777085ef75997040353a999e7253ee
Implements: blueprint commmon-openstack-database-resource
Defaults to ::processorcount
Also reseting puppet 2.6 compat in spec/classes/nova_db_postgresql_spec.rb
so that unit tests pass, it looks like our 2.6 unit test runner is using
puppet 2.7

This allows Nova to be used with PostgreSQL.
Requires the puppetlabs/postgresql module. NOTE: I did add this
dependency to fixtures but did not add it to the Modulefile due
to the fact that the postgresql::python module hasn't been
released to puppetforge yet (although it is committed and tests
pass).
