As one of RDO maintainer, I strongly invite kolla, not to use EPEL.
It's proven very hard to prevent EPEL pushing broken updates, or push
updates to fit OpenStack requirements.

Actually, all the dependency above but ansible, docker and git python
modules are in CentOS Cloud SIG repositories.
If you are interested to work w/ CentOS Cloud SIG, we can add missing
dependencies in our repositories.
