Distro-install tests for Ubuntu and Centos are voting now.

This patch makes available to completely move to zuul templates,
by adding openstack-ansible-role-distro_install-jobs into list.

Added small fixes to make them working.
Centos has gnocchi_resources.yaml packed with ceilometer-common package,
so test was failing on db_setup task.

Also ceilometer user was not created, as it checks for existance of
ceilometer_central_container group, which was not defined in inventory.
