protocol: Add framework to send transaction id with recall
Issue:
The upcall(cache invalidation/recall) event is sent from the bricks
to clients. In AFR/EC setup, it can so happen that all the bricks
will send the upcall for the same event, and if AFR/EC doesn't filter
out these duplicate notifications, the logic above cluster xlators
can fail.
Solution:
Use transaction id to filter out duplicate notifications.
This patch adds framework for duplicate notifications.
AFR/EC can build up on this patch for deduping the notifications
