YARN-3477 patch 002
# rethrowing runtime exception on timeout, but including the IOE as an
inner exception
# using constant strings in the error messages
# clean up tests to (a) use those constant strings in tests, (b) throw the
original exception on any mismatch, plus other improvements

> If timeline client fails more than the retry count, the original exception is
> not thrown. Instead some runtime exception is raised saying "retries run out"
> # the failing exception should be rethrown, ideally via
> NetUtils.wrapException to include URL of the failing endpoing
> # Otherwise, the raised RTE should (a) state that URL and (b) set the
> original fault as the inner cause
