chore: add a job that check that all other jobs are green on PR

[cbeauchesne]

Changes

• Enable Green CI Policy on dd-trace-py
• on label change, some check can become green -> exclude change log check, as it's already required
• on PR check list, some PR can become green -> exclude checklist check, as it's already required
• concurrency

This does not enforce checks on gitlab, for those, the required check on dd-gitlab/default-pipeline do the trick (eventually completed by other if needed).

Change

Added a job that verify the status of other jobs on the PR:

• If one of those jobs is pending, running or failed, this job fails.
• Once all jobs are finished in success, it succeed.

The next step, once we've validated it works correctly, is to make this job a requirement for merges. Side note, this solution has been implemented successfully on DataDog/dd-trace-js for one year.

I've removed Bootstrap import analysis from this check because it 20 PR has been merged with this job failing over the 195 PR on the last 60 days (success rate of 88%). Once this job is considered as healthy (or if we want to enforce it) we can remove it.

There are other jobs with a bad success rate, but they are not often included in PR, so TBD. Here are the jobs with a success rate lower than 95% :

• 95% (104) test
• 95% (187) dd-gitlab/check_pipeline_status
• 93% (30) dd-gitlab/contrib::dd_trace_api 1/4
• 93% (30) dd-gitlab/contrib::dd_trace_api 2/4
• 93% (30) dd-gitlab/contrib::dd_trace_api 3/4
• 93% (30) dd-gitlab/contrib::dd_trace_api 4/4
• 92% (200) dd-gitlab/default-pipeline
• 88% (195) Bootstrap import analysis
• 62% (8) dd-gitlab/contrib::dd_trace_api 1/1
• 0% (9) CircleCI Pipeline
