Log AUDIT events in Docker

[warrenvw]

Moved from https://github.com/StackStorm/st2enterprise-dockerfiles/issues/47

In a normal non-dockerized deployment, typical service logs vs AUDIT logs from the services are divided into different logfiles.

In Dockerized environment the established practice is to log to stdout/stderr.
At the moment we log to stdout only INFO loglevel events.
Consider including AUDIT logs as well.

Hi @armab I see this was opened more than 1 year back, just wondering if it's still the same or do we have anything separate for audit logs.

@manisha-tanwar Yes, this issue is still actual.
