Actually disable EPEL, and epel-modular

The disable_extra_repos macro accepts a list as its only argument. We
were calling it like this to disable EPEL:

disable_extra_repos('epel')

The macro interpreted this as a request to disable three repos, e, p, l.
Thanks Python! Type validation to be improved separately.

Additionally, on CentOS 8 the EPEL repository was not included in the
repository mapping file, repos.yaml. There is also another EPEL
repository on CentOS 8, epel-modular, which is enabled by default after
installing epel-release.

This change adds mappings for epel and epel-modular repos to repos.yaml,
and fixes the disabling of epel in the base image, as well as disabling
epel-modular.

There are some cases where EPEL is still used (it seemed a bit too
easy...), and the repository has been enabled for these images:

* bifrost-base (nginx)
* ironic-conductor (C7 only, shellinabox)
* freezer-base (C7 only, trickle)
* gnocchi-base (C8 binary only, python3-boto3)
* mariadb (pv)
* mongodb (C7 only, mongodb)
* nova-spicehtml5proxy (C7 only, spice-html5)
* telegraf (C7 only, python2-pip)

A few other things were changed:

* ironic-conductor does not require the ceph repo
* python3-pika is no longer installed in the openstack-base image
