We have a few places where we register license state listeners on
transient components (i.e., resources that can be open and closed during
the lifecycle of the server). In one case (the opt-out query cache) we
were never removing the registered listener, effectively a terrible
memory leak. In another case, we were not un-registered the listener
that we registered, since we were not referencing the same instance of
Runnable. This commit does two things:
- introduces a marker interface LicenseStateListener so that it is
easier to identify these listeners in the codebase and avoid classes
that need to register a license state listener from having to
implement Runnable which carries a different semantic meaning than
we want here
- fixes the two places where we are currently leaking license state
listeners
