Introducing Standalone context for running test in non-managed environment.

This patch introduces standalone virtualization context to
deploy/undeploy NFVi infrastructure to run the VNF

Supported NFVi Type:
  - vswitch
   - ovs
   - ovs-dpdk
   - sr-iov
   - testpmd
   - linuxbridge

This patches inits the function stubs to enable the standalone context.
Actual deploy/undeploy code will be added in later check-in

v2: Added unit tests to keep test coverage :)
