tests: Verify PIM RP on an FHR

[routingrocks]

Test PIM on a multi-VRF setup where the FHR is the RP. Verify the pimreg interface in VRF blue and red,
and multicast stream from H1 goes out on both the VRFs. Basically, this test verifies RP when the FHR is directly connected to the sender.

@routingrocks, we started doing unified configs since 10.0, is it possible to switch to using frr.conf instead of separate per daemon configs?. Once you have frr.conf you can load them like this:
