The Infra team has _strongly_ recommended against employing Git
submodules within repos hosted on our Gerrit instance in the past,
for a number of reasons.

If your primary concern is about making sure you integration test
kolla-ansible with kolla, using zuul-cloner to retrieve
corresponding refs for them in your jobs will provide a much more
complete picture of both. Your proposed submodule would only allow
you to test proposed changes for kolla-ansible against merged
changes in kolla, making it easier to break kolla-ansible when
merging incompatible changes to kolla and also robbing you of the
ability to rely on cross-repo change dependencies between both
repos.
