Add firing events to the procedure data models

[BeksOmega]

Problem Statement

The procedure data models need to fire events in response to change in their data so that devs can respond to these changes. E.g. sharing a procedure with another workspace in response to the creation of the procedure.

Important note: If there is no actual change to the procedure model (e.g. renaming "My Procedure" to "My Procedure") then no event should be fired.
