This patch adds Update Queue action into item_actions.
- show item action
- show workflow (set "name" input as disabled)
- load data into workflow
- post data to REST API
- treat result
We need wait for following implementation in Zaqar API,
so these things is not scope of this patch.
- provide available metadata
- remove existing metadata
