Similar to what we did here: https://review.opendev.org/#/c/655276 but,
for ceilometer/data/meters.d/meters.yaml file.
The idea is to create a method for operators to manage custom meters
YAML files via Kolla-ansible. To do that, we enable them (operators)
to use a folder called by default "meters.d" in their local
ceilometer configurations, where all of the custom meters YAML files
will be read from. If this folder exist and has YAML files in it, we
copy them for the default "/etc/ceilometer/meters.d" path in the
containers. We do not inject things in the container though. We copy
the files for the control node, and then we map them via
ceilometer*.json container configuration files.
