directly.

missing dependencies.

The pre-install operations may fail, yet that failure is not
elevated to the user. This masks the failure and makes early
package install issues difficult to troubleshoot.

If the basic pre-install script fails, the charm should not
proceed to later hooks as the requirements may not be met.

Hashbangs for bash should specify -e (errexit) on all of the
pre-install bash scripts.

The previous attempt at addressing Bug#1811108 was a bit naive.
It was not HA aware and it failed to handle upgrade-charm.

This change moves from kv to leader-set as only the leader needs to run
the action and then inform the other nodes.

Note: on upgrade-charm we must assume the deployment has run
ceilometer-upgrade as there is no mechanism to determine this
independently. If we do not do this, the charm is in blocked state after
charm-upgrade. A warning is logged that this assumption has occurred.

The charm currently configures events to be published to
rabbit on both the config.event_topic (event.sample queue)
and alarm topic but as of Queens Ceilometer no longer
consumes event.sample. This patch makes the event_sink
publishers configurable and defaults to publishing to
aodh to retain backwards compatibility.

Currently it is unclear that ceilometer is not actually ready when it
is related to gnocchi until the ceilometer-upgrade action has run. The
status will show active Unit is ready when it is not.

When gnocchi is related, check that the ceilometer-upgrade action has
been run. If not set workload status to prompt the administator to run
the action.

Use the generate_ha_relation_data helper from charmhelpers to
generate the data to send down the relation to the hacluster
charm.

This results in a few changes in behaviour:

1) The charm will no longer specify a nic name to bind the vip. This
   is because Pacemaker VIP resources are able to automatically
   detect and configure correct iface and netmask parameters based
   on local configuration of the unit.
2) The original iface named VIP resource will be stopped and deleted
   prior to the creation of the new short hash named VIP resource.

This change adds polling.yaml to the list of managed config files, for
Queens and above.  Two new config items are added alongside the
template, to take into account a choice between the two polling.yaml
files supplied with the Ceilometer source, one which has a small list of
pollsters and the other which has all pollsters.  Additionally the
change adds the option to set the polling interval.

We want to default to running all tox environments under python 3, so
set the basepython value in each environment.

We do not want to specify a minor version number, because we do not
want to have to update the file every time we upgrade python.

We do not want to set the override once in testenv, because that
breaks the more specific versions used in default environments like
py35 and py36.

This change adds the ability to listen for events across multiple
rabbit queues. Nova cells v2 has a message broker per cell and
the charms already support having a separate message broker for
neutron, in both these topologies ceilometer needs the ability to
listen to multiple brokers.

To achieve this a new relation 'amqp-listener' has been introduced.
The existing 'amqp' relation should be used for the broker that
ceilometer listens to and publishes to. 'amqp-listener' should be
used for additional brokers that ceilometer just listens on.

Update functional tests to satisfy relation with
nova-cloud-controller.

This is a mechanically generated patch to complete step 1 of moving
the zuul job settings out of project-config and into each project
repository.

Because there will be a separate patch on each branch, the branch
specifiers for branch-specific jobs have been removed.

Because this patch is generated by a script, there may be some
cosmetic changes to the layout of the YAML file(s) as the contents are
normalized.

Therefore, according to Transition Plan [1],
it'll be handy to have py36 testenv.
