Create CI parser for requirements job artifact

When user clicks the requirement manual job in CI pipeline, this job will produce an artifact - a CSV file which says that all requirements passed - e.g. *;passed;.

We need to add a CI report type and parser similar to other CI parsers (lib/gitlab/ci/parsers) to process these reports when pipeline finishes. This parser will iterate through all open requirements on the project and fills a "test report/confirmation" for each of them.
