The python-neutronclient is deprecated. We should use openstackclient
and openstacksdk for the equivalent functionality.

Alarm service has been moved to Aodh for a long time [1].
Therefore, we should define evaluation_interval in
aodh.conf rather than ceilometer.conf. The interval value
should be configurable as well because we can use a
custom polling config now [2]

Even though Kolla services are configured to log output to file rather than
stdout, some stdout still occurs when for example the container re(starts).
Since the Docker logs are not constrained in size, they can fill up the
docker volumes drive and bring down the host. One example of when this is
particularly problematic is when Fluentd cannot parse a log message. The
warning output is written to the Docker log and in production we have seen
it eat 100GB of disk space in less than a day. We could configure Fluentd
not to do this, but the problem may still occur via another mechanism.

oslo.messaging has removed deprecated options for rabbitmq.
one of the options is the vhost, which we do not define in
the transport_url.

The format for the Logstash Kafka output plugin worker count is
integer in Logstash 2 and string in Logstash 5. Since we have downgraded
Logstash we need to switch formats here.

To build the Monasca images, they need to be built from source, however,
this doesn't include Logstash. Logstash does not differentiate between
binary or source install types, so we can just use the default.

Increase the maximum payload size so that it slightly exceeds the default
maximum chunk size (8MB) in Fluentd. This prevents the Monasca Log API
dropping logs when under heavy load.

If the config option is not specified Monasca Notification defaults
to YAML config parsing and fails to load.

Quotes around {posargs} cause the entire string to be combined into one
arg that gets passed to stestr. This prevents passing multiple args
(e.g. '--concurrency=16 some-regex')

Since the configuration file of the panko module was referenced as a
variable during the deployment of the ceilometer module, the
project_name variable of the ceilometer module was overwritten,
resulting in an error when deploying the ceilometer module using the
development mode. This patch will fix this problem.
