Should we add unpause or just have start unpause it if it's in a paused state? Seems like kind of a silly context menu item to add.

[ejizba]

The terminology is coming directly from Docker, so I feel like we should be consistent. Also - in Docker we only display start/stop/restart/etc. for applicable items so it won't add any clutter. In other words "unpause" will only show for paused containers

[nturinski]

Oh right, your crazy dynamic context values

[ejizba]

Lol nah the crazy stuff is for registries. This is a pretty simple one that just adds "state" at the beginning here with an example reference in package.json here

It would probably be pretty easy to replicate for app service or functions if we want to hide start/stop/etc.
