This is a Logstash component which reads processed logs from Kafka
and writes them to Elasticsearch (or some other backend supported by
Logstash).

Ingesting the logs from this service with Fluentd will be covered under
a different commit.

The Monasca Log Transformer takes raw, unstandardised logs from one
Kafka topic, standardises them with whatever rules the operator wants
to use, and then writes them to a standardised logs topic in Kafka. It
is currently implemented as a Logstash config file.

Since Kolla does a fairly good job of standardising logs, this service
does very little processing. However, when other sources of logs
are used, it may be useful to add rules to the Transformer, particularly
if it's not possible to standardise the logs at source.

Ingesting the logs from this service with Fluentd will be covered under
a different commit.

Other lists of servers have the postfix _servers. To be consistent
this change uses the same format for Kafka.

Multiple Monasca services will need to access these topics. We
can use these variables to make sure that they all use the correct
ones.
