Disabling and suspension of accounts feature

[gabreal]

would be useful if the admin bot could help offboarding users.

common scenarios when offboarding: use admin/v1/deactivate/ for account deactivation (needed for sso and non-sso configurations.

sometimes accounts need to be suspended, then admin/v1/reset_password/ is used with random password and logout of devices (useful in non-sso scenarios -- log-out of devices would still be useful though with sso).

would also be useful to be able to check the deactivated status of a user, show logged in devices and set a password.
