feat(core/autocomplete): complete content of args using list verbs

[Codelax]

Keep it as beta for now, could crash completion

Will try to complete arguments using the list verb of the specific resource
Example:
In instance namespace, every server-id will execute instance server list and complete with id fields

In marketplace image get label=, it will fetch for label using list of current resource marketplace image list
