Following up with T5321, IGMP should also be made VRF-Aware.
To do so, protocols igmp should be made available inside the vrf name example_vrf configuration subtree.
Sanity checks should fail a commit when attempting to add an interface in a VRF if that interface isn't member of that vrf. Reciprocally, an attempt to commit the addition of an interface into the main protocols igmp should fail if the interface is member of a VRF.
Also, the following command subset is required to access details for a specific VRF: show ip igmp vrf example_vrf [...].
