Add ceilometer profile rspec testing

This change adds rspec testing for the ceilometer profiles. While
writing these tests, the tripleo::profile::base::ceilometer::collector
class needed to have the hiera lookups moved to class parameters to
allow for testing the possible options around the database backend.
These tests add coverage for ipv4 and ipv6 configurations for the
collector profile as well as excluding mongodb on the backend.
