As a Admin, I should be able to view the history of an existing stack

As a Admin, I should be able to view the history of an existing stack.

An stack once deployed, will be updated multiple times, as and when the user adds new requirements.
Now when more than one Admins are working on the stack, you would like to know the history till date, to get to know the changes done to this stack.

Hence when creating/updating an stack, there should be -m option, wherein you can provide an short message describing the changes done to stack.

And when the admin says something like:
heat stack-history <stack_name>

+-------------------------------+------------+-----------------------------------------------+--------------------------
| .....UPDATED_AT........ | ..USER.. | ....................MESSAGE............... | STATUS
+-------------------------------+-----------+-----------------------------------------------+-------------------------
| 2015-04-14T11:50:42Z | ADMIN1 | 'Stack with web server'................ | CREATE COMPLETE
| 2015-04-14T12:51:46Z | ADMIN1 | 'provided public IP to server'....... | UPDATE COMPLETE
| 2015-04-14T12:59:33Z | ADMIN2 | 'added HA to server'.................... | UPDATE FAILED
| 2015-04-14T01:01:36Z | ADMIN2 | 'Heat system generated: rollback' | ROLLBACK COMPLETE
| 2015-04-14T01:59:47Z | ADMIN2 | 'retry: added HA to servers'......... | UPDATE COMPLETE
+---------------------------------+-----------+----------------------------------------------+-----------------------------

Also note that the existing heat event-list <stack-name> does not give the stack level details, it is only resource events and are hugh in number once multiple updates are performed.
