mw/kubernetes: split integration tests (#1004)

Browse Source 
* 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
