Admins able to change status of agents

It would be useful for admins to have more abilities to change settings of users such as, changing their status. E.g. if system issue occurs for an agent and they cannot change their status, we would want to remove them from the queue by making them unavailable. Further, currently, the agents have the ability to change their own wrap-up time, this should be an option in permissions, to allow for admins to change this for a group or individuals and block the ability for users to change it themselves.
