Initial mdsal and config karaf features

This loads cleanly into karaf :)

Instructions for checking:

cd controller/

mvn clean install

cd opendaylight/distributions/opendaylight-karaf/target/assembly/bin
sh karaf

at the karaf prompt

feature:install odl-mdsal-restconf
feature:list -i

(odl-mdsal-restconf will pull everything else through).

PatchSet2:  Fixed failure to use odl- prefix in features for -all
