and make the other utility methods private as
we don't really need to use them outside of the job.

Given GitLab moves away from using the term build, everywhere, also the
CI variables are being renamed.

For now, both `CI_BUILD_X` and `CI_JOB_X` are supported, with the same
values. However, in about 3 months, support will be dropped.

This reverts commit e00fb2bdc2090e9cabeb1eb35a2672a882cc96e9.
