CORD-333 Minimized OVSDB provider dependency

With this patch, cordvtn doesn't need to care for OVSDB connection state
anymore. It will make a connection to OVSDB server like befor but just
for node init and disconnect the OVSDB right after init is done.
- Changed OvsdbNode to CordVtnNode
- Removed OVSDB connect/disconnect and added initNode instead
- Changed ovsdb* commands to cordvtn-node* command, and removed
  connect/disconnect command and added init instead
- Fixed to remove OVSDB device from the system after node init or before
  making a connection to work around OVSDB device re-connect issue
