Currently we cannot install the ceph-iscsi-ansible RPM on a node where
the ceph-ansible RPM is already installed.
ceph-iscsi-ansible should install on top of the ceph-ansible environment
without issues.
These are unnecessary on RPM-based platforms, and it makes it harder to
audit the RPM-packaged files for security when we ship things that are
unneeded.
This is the only version that our CI uses for testing, so it's the only
version we can confidently say works.
Update the RPM packaging to specifically require this version of
Ansible.
"make rpm" will build a ceph-ansible RPM and place it in the current
working directory.
This will allow us to run this command in Jenkins for every branch.
