Mixing binary and source images for C* projects

In case Kolla's users want to deploy with both of
binary and source image, we should have a variable
install type that define install type for each project.

We also add specific image tag for each Openstack project.

This commit is implemented for Ceilometer, Ceph
Cinder, Cloudkitty and Congress projects.
