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.

Various ceph-related tasks were missing a 'become' that would allow them
to work as a non-root user. This seems to only cause a problem after an
initial deployment, perhaps due to the recursive ownership & permissions
changes at the end of the ceph.yml and external_ceph.yml files.

This change adds the necessary becomes.

Cinder has dropped [1] support for legacy backup services. It is now
necessary to specify the full class of the backup driver, rather than
just the module name. This was causing the kolla-ansible ceph jobs to
fail.
