Ceilometer-upgrade is in a race with the keystone catalog for the
metric entry. The function already has a retry on error loop. Bump up
the delay between retries to mitigate the race with keystone.

Align ceilometer charm with worker-multiplier usage as found
across the majority of OpenStack Charms.  Worker configuration
values are set for API, Notification and Collector services
as needed for each release. Note that for Ocata or later, API
services are executed as WSGI apps under Apache which was
already plugged into the standard worker calculation logic
in charm helpers.

This includes dropping of the existing api-worker configuration
option in preference to a calculated approach.

Sync charm-helpers to pick up the updated InternalEndpointsContext
which removes the need to provide a package.

This essentially reverts commit f76d0755 in favor of an alternative
approach to selecting the volume catalog endpoint information.

Update charm to support Ceilometer@Queens; specifically:

 - Removal of Ceilometer API service
 - Removal of ceilometer-collector service

Most of this change is related to dropping of these
services; In addition its now possible to complete a
ceilometer-upgrade without mongodb being configured.

As this charm no longer provides any endpoints to
keystone, for Queens the identity-credentials relation
is required instead of the identity-service relation.

The default HAProxy timeout values are fairly strict. On a busy cloud
it is common to exceed one or more of these timeouts. The only
indication that HAProxy has exceeded a timeout and dropped the
connection is errors such as "BadStatusLine" or "EOF." These can be
very difficult to diagnose when intermittent.

This charm-helpers sync pulls in the change to update the default
timeout values to more real world settings. These values have been
extensively tested in ServerStack. Configured values will not be
overridden.

Bionic, being the next LTS, is important to enable for dev
and test as early as possible ahead of 18.02.

Zesty goes EOL in Jan 2018. The next stable charms release (18.02)
will not provide Zesty series support, as it was an interim
(non-LTS) release.

When an existing cluster of the service is scaled out the new unit
will join with keystone before it is fully clustered. In identity
joined hook the charmhelpers function canonical_url is called which
in turn uses another charmhelpers function, resolve_address.
resolve_address will only return the vip if the vip is set in config
AND the unit is clustered. This means that the units local address
is returned and that is then registered with keystone.

This change gates registering an endpoint if the cluster is
partially formed.

The OpenStack OCF resource definitions for Ceilometer have proven
to be quite brittle, and we can achieve much the same end by just
using the lsb module to track ceilometer-agent-central directly.

Drop all use of ocf:openstack and delete res_ceilometer_polling
which is a) broken for Pike and b) complete misnamed.  Configure
'lsb:ceilometer-agent-central' for all deployments irrespective
of release.

The default value of event and meter_dispatchers were "database"
implicitly. However with Newton, there is no default value for
event_dispatchers. And empty meter_dispathers with Ocata. While Gnocchi
and Panko are preferred solutions, keep backward compatibility to
support an upgrade for existing deployments with MongoDB.

event_dispathers is not needed for Ocata since v2/events API has been
removed completely from Ceilometer.

Add new metric-service interface to support use of
Gnocchi as a storage backend for resource and metric
data.

Configure ceilometer to use the gnocchi dispatcher
in the event that ceilometer is related to gnocchi.
This has the side effect of disabling the ceilometer
API - Aodh and Gnocchi API's should be used directly
in this deployment topology.

Note that Gnocchi is only supported in OpenStack
Mitaka or later; 'metrics-service' is added to the
required interfaces configuration as an alternative
to 'mongodb' for >= Mitaka.
