CA-136173: Getting several notifications for one user-level action (e.g. Updating network operation creates 4 entries in the Notifications/Events view)

-  Suppress reporting of success and failure for sub-actions:
The suppress history flag is set when the action is created and if is false (by default) the action is added to the history (the Events list).
In order to suppress history for the subactions, we need change all actions used in Edit pages so their constructor can set the SuppressHistory flag and then use these constructors with suppressHistory = true on all the implementations of IEditPage.SaveSettings() where an action is created
(then we need to remember to do the same everytime we introduce a new page and / or "save" action).

- Multiple action: propagate error messages back up the action tree to the parent action.

- Set the pool details in the action to allow proper filtering by location on the Events page
- Also, when possible, set the Host property: when setting the SR in the action, we also set the Host to SR.Home
