[Feature Request] Add a script for re-provisioning online APs

Currently, reprovisioning has to be done using the web frontend which doesn't have a dark theme and thus is ugly as hell.

I propose a script to safely re-provision an online AP with the following design:

• The AP doesn't get reprovisioned if there are clients connected to the AP, unless --force|-f is specified.
• The AP is identified either using its MAC-address --mac, switchport --switchport or name --name.
• For provisioning, the following options can be set, where only those options need to be set which actually differ from the current AP configuration:
  • --new-name – the new name of the AP
  • --ap-group – the new group for the AP to be in
• An option --wait-until|-w might be specified to make the script wait until the specified point in time before provisioning the AP.
• An option --lazy|-l might be specified to make the script wait for all clients to become disconnected from the AP before provisioning it. If --wait-until|-w is also specified, the script shall force-provision the AP after the wait time has expired, but may provision it earlier if all clients are disconnected from the AP.
