Karaf features for OVSDB modules.

Karaf features for OVSDB modules.

1. Individual Features for library, schema wrappers and plugin.
2. Northbound and Openstack features will be added as soon as controller AD-SAL karaf features are resolved.
3. Updated proper <name> tag in each of the pom files as the default karaf behaviour is to print artifact-id in bundle:list.
