The ntp role attempts to mask NTP services that may conflict with
chrony. Currently we are seeing the following failure:

    TASK ntp : Mask alternative NTP clients to prevent conflicts
    Could not find the requested service systemd-timesyncd.service: host

The service_facts module shows that the service is not found:

    "systemd-timesyncd.service": {
        "name": "systemd-timesyncd.service",
        "source": "systemd",
        "state": "stopped",
        "status": "not-found"
    },

According to the Internet, this can happen if there are After/Before
dependencies in one service on another that does not exist.

This change fixes the handling of these not-found services to avoid the
error.

Currently we use the HEAD reference for OpenStack requirements. This can
create images that are incompatible with your version of OpenStack.

Variable untemplated_dirs has been added to allow for
defining directories under kayobe/kolla/config which should be copied
instead of templated by kolla-openstack role.

This is needed to support custom themes for horizon -

The chrony container removal was performed in the Xena cycle, so we no
longer require this in the 'overcloud host configure' command.

A double colon (where only a single colon is wanted) was fouling up

EPEL is no longer required for a default installation. Let's disable it.

Also clean up the install_epel variable from Kolla Ansible globals.yml

ironic-python-agent-builder has stable branches since Wallaby -
let's use them.

Also as per ipab docs [1] - the env vars for overriding ipa repo
are:
- DIB_REPOREF_ironic_python_agent
- DIB_REPOLOCATION_ironic_python_agent
