pimd: Implement watermark warning for igmp group count and add igmp group count
This CLI will allow user to configure a igmp group limit which will generate
a watermark warning when reached.
Though watermark may not make sense without setting a limit, this
implementation shall serve as a base to implementing limit in future and helps
tracking a particular scale currently.
Testing:
=======
ip igmp watermark-warn <10-60000>
on reaching the configured number of group, pim will issue warning
2019/09/18 18:30:55 PIM: SCALE ALERT: igmp group count reached watermak limit: 210(vrf: default)
Also added group count and watermark limit configured on cli - show ip igmp groups [json]
