tests: Verify PIM RP on an FHR

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. Signed-off-by: Rajesh Varatharaj <[email protected]>
