Ping on every request causes the backend to be slow

[bernhardberger]

Please remove the ping() on every request in the backend (service 'isAvailable'). This causes the backend to do a ping on every single request and causes the backend to be super slow and unresponsive in a lot of scenarios..

I don't even think the ping is neccesary as the authentication service tries to connect on auth anyways and falls back to the other services if it times out..

I think there even is a pull request available for this: 777e23b
