Distribution directory commits and Jenkin's changes

Ed Warnicke (eaw) <eaw@...>

I pushed two changes to add a distribution directory:

https://git.opendaylight.org/gerrit/#/c/784/ - which adds the distribution directory and makes commons/ build both ovsdb/ and distribution/
https://git.opendaylight.org/gerrit/#/c/785/ - which moves commons/ to commons/parent so there's room for other 'commons' things

They both verify currently, but I would recommend if  you choose to merge them that you alter the Jenkin's Job to build the pom file:
commons/parent/pom.xml (as that should build all modules, ovsdb/ and distribution/ ).

Please also note the new top level README which has instructions analogous to what is provided in controller.
