Support Uptime Kuma for monitoring

[JvdMaat]

Can you add push notifications for Uptime Kuma?
From what I can tell, in Uptime Kuma we'd need to just create a push notification monitor with a x hour (time between backups plus some slack for slower backup runs) heartbeat interval. And from this container, it's just a matter of pushing:
https://uptimekuma.domain.com:3002/api/push/SECRETCODE?status=up&msg=OK (if it succeeded)
https://uptimekuma.domain.com:3002/api/push/SECRETCODE?status=down&msg=ERRORMESSAGE INFO (If failed).
And this could either be a global thing (in which case the error message would need info on which DB it is related to for a failure), or a unique monitor per DBxx
(The variable to provide to this container would be the Push URL (Uptime Kuma provides it as "https://uptimekuma.domain.com:3002/api/push/SECRETCODE?status=up&msg=OK&ping=", so that's what most people would copy/paste from Uptime Kuma)
