This lets pants detect the dependency
This allows pants to know which test uses this fixture.
Let pants know that these runners are in use for these tests
Let pants know where to get these conf files. Note that these conf files are not the same as the files in the repo root: //conf/st2.tests*.conf

Background
I'm working towards introducing
pants. Eventually I would like to use pants to run tests to take advantage of the fine-grained per-file caching of results that accounts for dependencies by python files (pants infers the deps by reading the python files).In order to use the fine-grained caching, Pants needs to know which tests rely on which fixtures. We could add extra metadata to tie the tests to the fixtures, but that would be an additional maintenance burden that will become out-of-date. We can also include all fixtures for all tests, but then we don't benefit from the fine-grained per-file caching. However, pants can already infer dependencies based on python imports, so that is what this PR (and several follow-up PRs) takes advantage of.
Overview
This PR does the following:
__init__.py.fixture.pyfile in each fixture that uses the fixturesloader utils (where helpful) to identify itself withPATHandNAMEvars.PATHand/orNAMEvars from that fixture.Follow-up PRs will address other fixture packs and other sets of fixtures. I will submit those PRs after this one is merged.
