* mw/kubernetes: split integration tests
* separate file and test for api fallthrough, does not need all other
servers to be started.
* more split ups: make it clear when or when not we need an upstream server,
as just needlessly start it in doIntegrationTests.
* use identifiers from dns package -> "TypeSRV" -> dns.TypeSRV, as there
is no need to reinvent these.
* updates
* deploy work-around
* re-add weird sleep
