[FR] PUI - Add option for plugins to add header actions

[matmair]

Please verify that this feature request has NOT been suggested before.

• I checked and didn't find a similar feature request

Problem statement

Plugins do not have a way to add quick action to the header action of items. Therefore users need to click at least twice to issue a plugin action once they are on the page for the item.

Suggested solution

Add a way for plugins to expose 0 or more custom actions for (specific) items

They should at least be able to set:

• Text
• Icon
• Tooltip text

To enable some transparency I think all plugin action should have a standard information from which plugin the action is emitted added to its tooltip

@wolflu05 any input on this?

[wolflu05]

Yes, that's exactly what I was planning to add with the custom UI feature system. I have added some more detail on how I imagined the system in #8278 (comment)
