Fix bug in sdnnetwork capability implementation and driver.

- Make internal driver GetAllocatedFlowsAction return an ActionResponse with status set to OK.
- Avoid IndexOutOfRange in OFProvisioningNetworkCapability when creating an ActionException if action response is not OK.
Remove NCL provisioner mockup.

It is no longer necessary.
It was being injected by error in NCLProvisionerTest, instead of actual provisioner.
NCLProvisionerTest now checks sdnnetwork and switches are updated when nclprovisioner is called.
WS test for OpenflowForwardingCapability in switches and OFProvisioningNetworkCapability in sdnnetworks.
Register OFProvisioningNetworkCapability as an OSGi service and expose it through WS.
Fix error in test. Add switchId to created forwarding rules.
Give time for dosgi to register/unregister WS before next test.

Without this workarround, some WS tests were accessing capabilities from previous tests,
resulting in internal failures, such as resource not found.
