Added test-provider project.

Added test-provider project.

This creates a bundle which:
1)  Provides a dummy listner for SalFlowService
2)  Provides an osgi command loadFlowData
that will write data to the MD-SAL for flows.

Patch 2:  Added commands for removing and modifying the
test flow.

To use, from the OSGI console type:

addFlow
modifyFlow
removeFlow

and you will see log messages indicating the dummy
rpc handler has received the rpc calls.

This basically tests the round tripping through the MD-SAL,
{add,modify,remove}Flow write data modifications for flows
to the tree, and then you see the RPC calls routed in the logs.

Very useful for testing.
