Eventing : Need a way to specify LCB log level

Currently eventing consumer, which uses libcouchbase, does not provide any way to bump up the SDK log level. As a result, there are times when the end user might just end up seeing the error codes thrown from the SDK to the consumer, which is not always helpful.

Would be great if by default consumer pushes all SDK info level logging to a separate file - maybe something like eventing-lcb.log, and provides the end user with an API to dump up LCB log level. I agree that this might require a consumer restart, but this would greatly help in debugging issues like network between eventing consumer and Query Engine / memcached etc.
