Timeline scenario action

[KiboOst]

Just like message or log action, having a timeline action would create an entry in timeline

options:
folder: user defined
type: scenario
subtype: info
linnk_id: scenario id
name: user defined (a field for object selection, then input field for custom message)

Of course we can create a virtual for that, but would be lot more heavy ... Such action who help a lot following important stuff in timeline.
