Block user through HTTP API (#846)

The new functionality allows blocking a user in the Management service.
Blocked users lose access to the Dashboard, aren't able to modify the network map,
and all of their connected devices disconnect and are set to the "login expired" state.

Technically all above was achieved with the updated PUT /api/users endpoint,
that was extended with the is_blocked field.
