[QUARKS-131] [WIP] supply an alias for a stream's control services
Looking for feedback for changes to the API.
Impl will follow once this is settled.
Note: relocated PeriodicMXBean as pure Topology/TStream users should not
have to know anything about the quarks.oplet domain.

> need easy way to get PeriodicMXBean associated with a poll() invocation

> I think we're missing some API is missing to make this all usable.
> A Topology/TStream domain user needs an easy way to get the PeriodicMXBean
> for a particular Topology.poll() invocation.
> The PeriodicSource oplet implements PeriodicMXBean which allows changing the
> period.
> The only demonstrated use is by
> DirectJobTest.jobPeriodicSourceCancellation(), which iterates over the
> Topology's underlying graph for instanceof PeriodicSource oplet (it's the
> only ProcessSource oplet in the graph for this test).
> That's certainly not easy / convenient / nor in the "TStream" domain the user
> is mostly operating in.
> [~djd] [~vdogaru] what schemes for addressing this have already been
> considered / decided? Some sort of "control bean registry service" where a
> user gets to supply a name (e.g., to poll()) and the runtime registers the
> bean (e.g., PeriodicMXBean) under that name? If there's not a concrete plan
> lets work on that here.
