pimd: header changes to cache MLAG information needed for pim-vxlan

This information will come in from a MLAG component. Hidden commands
will also be provided for testing the interface independent of the
separate MLAG component.

PS: It is possible that this cache will be merged with the base
pim-mlag datastructures once they are available.
