[openstack-dev] [OpenStack-Dev] [third-party-ci] Clarifications on the goal and skipping tests

A few reasons, I’m sure there are others:

- Broken tests that hardcode something about the ref implementation. The test needs to be fixed, of course, but in the meantime, a constantly failing CI is worthless (hello, lbaas scenario test.)
- Test relies on some “optional” feature, like overlapping IP subnets that the backend doesn’t support.  I’d argue it’s another case of broken tests if they require an optional feature, but it still needs skipping in the meantime.
- Some new feature added to an interface, in the presence of shims/decomposed drivers/plugins (e.g. adding TLS termination support to lbaas.) Those implementations will lag the feature commit, by definition.

The whole point of third party CI as I recall was to run the same tests that we run in the official Gate against third party drivers.  To me that would imply that a CI system/device that marks itself as "GOOD" doesn't do things like add skips locally that aren't in the tempest code already?

So the goal (using Cinder for example) was to be able to say that any API call that works on the LVM reference driver will work on the drivers listed in driverlog; and that we know this because they run the same Tempest API tests?
