tango.drone.openwrt.ninja OAuth apps removal

[Etienne Champetier]

Hi All,

I just deleted 'tango.drone.openwrt.ninja' from OpenWrt GitHub organization,
It had 0 users, no recent activity and the callback url pointed to
"http://tango.drone.openwrt.ninja/authorize", openwrt.ninja domain is
currently for sale
(https://shop.gandi.net/en/domain/suggest?search=openwrt.ninja)

We also have 'Transistion bug tracker' that is not used but it point
to a valid OpenWrt domain so we can keep it around

Best
Etienne
