Epic Goal

Currently, microshift hardcodes the ovnkube logs to log-level to 4. Goal is to make this configurable, e.g. in the ovn.yaml config file where the MTU is set, or by re-using the "debugging.logLevel". In general, more fine grained control (i.e., its own parameter) is better, to avoid spamming of logs. 

Why is this important?

Log Levels should never be hard coded, to allow for changes for better supportability.

Acceptance Criteria

• Ovnk log level not hard coded any more
• If new cfg parameter, docs needs to be updated.
