WIP: remove some ci environment variables

[6543]

remove some environment variables who are either the same value or make no sense to exist in the first place:

CI_STEP_STATUS
CI_STEP_FINISHED
CI_PIPELINE_STATUS
CI_PIPELINE_FINISHED

Could we remove those things just-in-time when we release 3.0. Those PRs will probably be quite outdated and need updates as we are constantly adding new deprecations til we release 3.0.

We should do 3.0 soon I think. There are enough breaing changes and deprecations collected. Maybe after 2.7.0?

I would like to like to do it earliest end of the year. We should provide the community some time between major releases and the breaking changes we would currently apply aren't that critical IMO and the benefits from a users perspective are rather minimal atm.

I would add DRONE_* to the list.

We keep the drone vars to be compatible to drone plugins.
