Move and update the cloud configuration unit tests.
Add a `deploy_scripts_search_path` test case.

Set default HWM in API call as well

@basepi set the HWM to 1000 by default in #8804 and this is a
complementary commit to that one. It is now obvious that the HWM is 1000
by default in the source code.
