Normalize Bundle Naming

Remove underscores and capitals from bundle names.
Remove duplicated "ovsdb" in bundle names.

This produces the following bundles:
- org.opendaylight.ovsdb.library-1.0.0-SNAPSHOT.jar
- org.opendaylight.ovsdb.neutron-0.7.0-SNAPSHOT.jar
- org.opendaylight.ovsdb.northbound-0.6.0-SNAPSHOT.jar
- org.opendaylight.ovsdb.plugin-1.0.0-SNAPSHOT.jar
- org.opendaylight.ovsdb.schema.hardwarevtep-1.0.0-SNAPSHOT.jar
- org.opendaylight.ovsdb.schema.openvswitch-1.0.0-SNAPSHOT.jar

This is consistent with the existing bundle naming in Nexus

This commit also fixes import issues with Eclipse...
