Description

Currently ui report network (ajax) errors with a common error code (-1).

Those errors should have unique codes to ease the identification of the api request that caused the error.

Also, to explore:
Distinct handling of errors based on the error code.
Possibilities:
a) handle the first request timeout in a different way compared to the next ones (retry vs. report error)
b) handle HTTP 400 differently for ?changes-since vs. full GET /servers requests (retry full GET vs. report error)
