The merge_configs action plugin is updated with an option to control
whether whitespace should be used around equal signs. The default
remains to use whitespace: only zookeeper.cfg doesn't use them.
This is to avoid issues with the zkCleanup.sh script which expects no
whitespace. The ZooKeeper documentation also uses no whitespace in
configuration file examples.

Closes-Bug: #1917490
In services which use the Apache HTTP server to service HTTP requests,
there exists a TimeOut directive [1] which defaults to 60 seconds. APIs
which come under heavy load, such as Cinder, can sometimes exceed this
which results in a HTTP 504 Gateway timeout, or similar. However, the
request can still be serviced without error. For example, if Nova calls
the Cinder API to detach a volume, and this operation takes longer
than the shortest of the two timeouts, Nova will emit a stack trace
with a 504 Gateway timeout. At some time later, the request to detach
the volume will succeed. The Nova and Cinder DBs then become
out-of-sync with each other, and frequently DB surgery is required.
Although strictly this category of bugs should be fixed in OpenStack
services, it is not realistic to expect this to happen in the short
term. Therefore, this change makes it easier to set the Apache HTTP
timeout via a new variable.
An example of a related bug is here:
https://bugs.launchpad.net/nova/+bug/1888665
Whilst this timeout can currently be set by overriding the WSGI
config for individual services, this change makes it much easier.

Closes-Bug: #1917648
This change allows a user to forward control plane logs
directly to Elasticsearch from Fluentd, rather than via
the Monasca Log API when Monasca is enabled. The Monasca
Log API can continue to handle tenant logs.
For many use cases this is simpler, reduces resource
consumption and helps to decouple control plane logging
services from tenant logging services.
It may not always be desired, so is optional and off by
default.

The Monasca alerting pipeline provides multi-tenancy alerts and
notifications. It runs as an Apache Storm topology and generally
places a significant memory and CPU burden on monitoring hosts,
particularly when there are lot of metrics. This is fine if the
alerting service is in use, but sometimes it is not. For example
you may use Prometheus for monitoring the control plane, and
wish to offer tenants a monitoring service via Monasca without
alerting and notification functionality. In this case it makes
sense to disable this part of the Monasca pipeline and this patch
adds support for that.
If the service is ever re-enabled, all alerts and notifications
should spawn back automatically since they are persisted in the
central mysql database cluster.

The Log Metrics service is an admin only service. We now have
support in Fluentd via the Prometheus plugin to create metrics
from logs. These metrics can be scraped into Monasca or Prometheus.
It therefore makes sense to deprecate this service, starting by
disabling it by default, and then removing it in the Xena release.
This should improve the stability of the Monasca metrics pipeline
by ensuring that all metrics pass via the Monasca API for
validation, and ensure that metrics generated from logs are
available to both Prometheus and Monasca users by default.

Historically Monasca Log Transformer has been for log
standardisation and processing. For example, logs from different
sources may use slightly different error levels such as WARN, 5,
or WARNING. Monasca Log Transformer is a place where these could
be 'squashed' into a single error level to simplify log searches
based on labels such as these.
However, in Kolla Ansible, we do this processing in Fluentd so
that the simpler Fluentd -> Elastic -> Kibana pipeline also
benefits. This helps to avoid spreading out log parsing
configuration over many services, with the Fluentd Monasca output
plugin being yet another potential place for processing (which
should be avoided). It therefore makes sense to remove this
service entirely, and squash any existing configuration which
can't be moved to Fluentd into the Log Perister service. I.e.
by removing this pipeline, we don't loose any functionality,
we encourage log processing to take place in Fluentd, or at least
outside of Monasca, and we make significant gains in efficiency
by removing a topic from Kafka which contains a copy of all logs
in transit.
Finally, users forwarding logs from outside the control plane,
eg. from tenant instances, should be encouraged to process the
logs at the point of sending using whichever framework they are
forwarding them with. This makes sense, because all Logstash
configuration in Monasca is only accessible by control plane
admins. A user can't typically do any processing inside Monasca,
with or without this change.

The Cinder API log is currently written to a file called
cinder-wsgi.log, and the WSGI logs to cinder-api.log. Fluentd
then tries to parse the WSGI log as an OpenStack log which
results in 'got incomplete line' errors and prevents proper
ingestion of these logs.

it was confused to customize opts in trove-conductor.conf
or trove-taskmanager.conf now.
if we want to customize a opts,The operator needs
to know which service is using the configuration opts.
actually trove uses trove.conf is enough for all services
this change combines all trove config files.
