    Description

      There is excessive (debug) logging in Brooklyn.

      As an example, I took a QA test that deploys a medium-sized blueprint, runs a few assertions against it, and tears it down (within an hour). That test has 280,724 lines at debug or above. As another example, in a long-running Brooklyn server the debug log rolls frequently (with 10 rolling log files of 100MB each, we have only 9 hours of logs).

      Taking that first example, here are a few counts of line numbers that appear a lot.

      There are 3352 lines during startup of the form:

      2018-01-16T10:18:39,356 DEBUG 120 o.a.b.c.b.s.c.BrooklynEntityMatcher [tures-1-thread-1] Item Service[name=Quarantine Group,description=A grouping for entities that are in quarantine (i.e. removed from the main cluster),serviceType=org.apache.brooklyn.entity.group.QuarantineGroup,characteristics=[],customAttributes={}] being instantiated with org.apache.brooklyn.entity.group.QuarantineGroup
      

      There are 3068 lines (after startup) of the form:
