Update git submodules

* Update docs/submodules/sdnvpn from branch 'master'
  - create log file during logger initialization
    
    Currently the log messages from utils and openstack_utils
    python modules are not logged into bgpvpn.log. This is
    because this file is created during SDNVPN Feature
    initialization. So creating this file during logger
    initialization itself.
