Feature/osgi config creator

Framework for defining OSGi configs via the AEM Tools UI with Dispatcher Flush Rules config implementation as an example. Other OSGi components can have configuration (CQ) components to leverage this tooling.

As long as the EventHandler is running on Publish, OSGi configs can be defined on author and activated (or packaged and deployed).

Previously discussed in Issues #78 and #93 

* Unit tests pending feedback from team.
* Needs ~~checkstyle, package-info~~ and java-docing for `OSGiConfigConstants`
* ~~ClusterAware isMaster check for EventHandler to ensure it only runs on master~~
* ~~Template icon for OSGi Configuration utility page~~
* ~~Component icon for Dispatcher Flush Rule Config~~ (decided default is most appropriate)
