xci: Exclude aodh, ceilometer, and gnocchi from deployments

xci: Exclude aodh, ceilometer, and gnocchi from deployments

Aodh is broken on the master branch due to use of conflicting
sqlAlhcemy package, causing issues during osa repo_build.

This patch disables aodh and the related services ceilometer
and gnocchi since the reason for us to have these 2 is to get
aodh.
