Commit API - Commit without triggering pipeline

Problem to solve

When committing file(s) via the commits API, there's no option to do so without also triggering a push to remote pipeline.

Intended users

Users pushing generic commits to projects not intending to trigger a pipeline

User experience goal

The user should be able to set ci.skip as an option when committing file(s) using the commits API.

Proposal

add 'ci_skip' as an boolean attribute to the commits api object POST /projects/:id/repository/commits
