Add support for P4Runtime clone sessions via Group API
Clone sessions can now be created by defining groups with new type CLONE
The PI framework has been refactored to abstract commonality between
multicast groups and clone sessions as both are managed as part of the
P4Runtime packet replication engine (PRE).
