Adding controller ADSAL & NSF features

Adding controller ADSAL & NSF features

1) Feature Tests Pass:
https://jenkins.opendaylight.org/controller/job/controller-merge/org.opendaylight.controller$features-adsal/2652/testReport/
https://jenkins.opendaylight.org/controller/job/controller-merge/org.opendaylight.controller$features-nsf/2652/testReport/

2) Features Comply with Guidelines: Yes (features starts with odl-, with description & no Start-levels)
        https://git.opendaylight.org/gerrit/gitweb?p=controller.git;a=blob;f=features/adsal/src/main/resources/features.xml;h=e12ca8e5e990acc860dc9e56e4eed57ed9c2a0e0;hb=a2670916a9c216311479463bbe2d707444afedc5
        https://git.opendaylight.org/gerrit/gitweb?p=controller.git;a=blob;f=features/nsf/src/main/resources/features.xml;h=8dc51f1644c48dd31e9bf911681ea6819d7dc32b;hb=a2670916a9c216311479463bbe2d707444afedc5

3) Features Tested: Features have been tested for functionality with
	a) feature:install odl-adsal-all
	b) feature:install odl-nsf-all

4) Integration Test Impact : This brings in ADSAL & NSF bundles. Since we dont have any AD-SAL southbound plugin features yet,
                             It will be difficult to run any existing test to make a difference. As soon as we have OVSDB or
                             ADSAL-Openflow or MD-SAL adaptor features available, we can start to see results :-).
