The ceilometer compute agent uses the default polling.yaml
from the installed packages without the ability to configure its contents.
This change adds two configuration options: 'polling-interval' and
'enable-all-pollsters', borrowing from the implementation in
charm-ceilometer. We start off with a limited set of meters as before
and if these are not enough, the user can set 'enable-all-pollsters' to
'true' to collect all available 'Pollster' metrics as listed in the
documentation [1].
Verification:
I tested this change on a cluster built from the OpenStack base bundle
and the ceilometer and gnocchi charms. I confirmed that extra metrics
that originate from the Compute Agent pollster (e.g. disk.device.read.latency)
are available in gnocchi after setting 'enable-all-pollsters' to true.

Samples collected can be batched together,
consequently increasing or reducing the
amount of API calls and body data
sent to the configured publisher.
This config is available since Rocky,
receiving the value from ceilometer-charm
to allow its tuning.

If rabbitmq is deployed in a cluster then the ceilometer charm will
pass rabbitmq_hosts and rabbitmq_host to ceilometer-agent. This charm
was ignoring the rabbitmq_hosts key and thus always talking to a
single rabbit even if there were multiple.
