MINOR: reg-tests: add base prometheus test
Add a base test to start with something, even though this is not
necessarily complete.
Also make use of the recent REQUIRE_SERVICE option to exclude it from
test list of it was not build with prometheus included.
note: I thought it was possible to send multiple requests within the
same client, but I'm getting "HTTP header is incomplete" from the second
request
