Monasca Python service logs prior to this change were being dropped
due to missing entries in the Fluent record_transformer config file.
This change adds support for ingesting those logs, and explicitly
removes support for ingesting Monasca Log API logs to reduce the risk
of feedback, for example if debug logging is turned on in the Monasca
Log API.
