allow specifying url_suffix per-case
Created by: wizardofoz123
Currently, if url_suffix is set in suite, all cases get tests-beaker fetch element, with url_suffix set. If url_suffix is missing, the fetch element is not present.
This patch allows to set url_suffix per-case. If it is present in both suite and case, then case overrides suite.
This requires complementary kpet-db change.
