Add support to install distro packages from RDO CloudSIG repos

RDO provides two sets of repositories with OpenStack packages, RDO Trunk
and RDO CloudSIG [1]. Currently, openstack_hosts role always uses Trunk
repos but in some cases, users may prefer to use CloudSIG.

This patch adds a variable openstack_hosts_rdo_repo_type which can take
values "trunk" or "cloudsig" to select the type or repos to be used.
