Expose a job's tag list on the Jobs API

Problem to solve

There is currently no visibly of a job's tag list.

Further details

This would allow for looking up jobs that have a certain tag.

Proposal

Expose a jobs' tag list on the Jobs API

What does success look like, and how can we measure that?

A jobs' tag list is included with a job over the Jobs API eg. /api/v4/projects/23/pipelines/8725/jobs would have the following included in the response.

tag_list: [
  "TagA",
  "TagB"
]
