    [WIP] [QUARKS-22] [COMMENTS?] StreamScope

    Open for comments on "API", behavior and impl (where not marked as TODO).
    The DevelopmentProvider adds StreamScope peekers.
    StreamScope's will be registered with a new StreamScopeRegistry runtime 
service.
    The Console will lookup a stream's StreamScope (to enable&configure) via 
the StreamScopeRegistry by its associated stream's alias or stream id.
    Still working out the details of StreamScopes getting registered to make 
lookupBy streamAlias or id possible.
    
    - Add PlumbingStreams.StreamScope (Consumer<T>)
    - Add PlumbingStreams.StreamScopeRegistry
    - Add quarks.topology.plumbing.StreamScope oplet (just so console can
    present it differently - remove?)
    - Update DevelopmentProvider to add StreamScopes
    - Add StreamScope and StreamScopeRegistry tests

> Something I would like to be able to add to the console is a way for the user 
> to be able to visualize the tuples flowing through a stream.  In this 
> document:
> https://github.com/quarks-edge/quarks/wiki/Quarks-Etiao-Runtime
> There was a mention of this under the graph transformations section:
> Addition of tuple view capabilities (to allow developers to see tuples on a 
> stream in a console). 
> The console needs the underlying api in order to do this.
