On charm upgrade the charm may switch to py3 packages. If so, ensure
the old py2 packages are purged. If the purge occurs then restart
services.

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.

package was installed to determine the OS release. On queens deploys
this breaks due packages not being installed.

If ceilomter-common is not installed return empty configs.

There is a use-case to forward events received by ceilometer from
OpenStack services to an external system via http/udp. It comes
from the fact that aodh does not include all information about an
event alarm into POSTed data. Raw event data can be published by
ceilometer via http/udp to an external system without giving a
user direct access to rabbitmq.

This patch adds a context generator, associated templates, and
configuration entry for configuring multiple event-sinks in
/etc/ceilometer/event_pipeline.yaml. This also modifies the
ceilometer.conf templates to reflect the correct naming of the
same file to align with upstream Ceilometer.

Also adds support for a future Panko charm event consumer using
the event-service interface in the above context with associated
metadata and hook symlinks.

This change will only effect Mitaka and later clouds.

As of pip 10.0, --allow-unverified is not permitted.

Use of the flag in this repo was previously used to force
installation of python-apt to accommodate certain unit tests.

The unverified package, python-apt, is no longer necessary

The ceilometer-upgrade command needs to be run to update back end
ceilometer data stores. When attempting to run this command during
deploy time due to the number of required relations many inherent
race conditions exist leading to Bug#1749280.

This change allows the ceilometer-upgrade command to be run as an action
post-deploy.

rather than the identity-service relation. When using HTTPS
