[jdk11u-dev] RFR: 8286293: Tests ShortResponseBody and ShortResponseBodyWithRetry should use less resources [v2]

[Goetz Lindenmaier]

> I backport this test-only change for parity with 11.0.17-oracle.
> 
> I did the following adaptions:
> ShortResponseBody.java
> * Adapt test run specification to requirements of 11.
>   This did not match in this file, but all other files
>   needed fixes, too.
> * Resolve includes
> * Removal of four methods did not apply clean.
>   The methods were moved to the new files.
>   I dropped the old implementation and am using the 
>   new ones in the new files except for assertExpectedMessage()
>   which is not in 11.
> 
> ShortResponseBodyPostWithRetry.java
> * test run specification: different context
> 
> Tests are compiling and passing.
