[JENKINS-65071] Closing a github PR should not trigger tags examination

I started to notice that our github app key quota gets exhausted. When this happens usually is because Jenkins is doing a full examination of the repository, and since I have a lot of tags (2k+), this process takes a while (10mins) and depletes the quota.

From checking the Multibranch Pipeline Events logs I can see that tags are being processed, but usually it is hard to understand what triggered this. However today I managed to reproduce this by closing a PR (not merging). Here are the logs

 

 

```
[Wed Mar 10 11:55:06 UTC 2021] Received Pull request #16349 closed in repository xxx/platform REMOVED event from 140.82.115.242 ⇒ https://jenkins.xxxx.com/github-webhook/ with timestamp Wed Mar 10 11:55:01 UTC 2021
11:55:06 GitHub throttling is disabled, which is not allowed for public GitHub usage, so ThrottleOnOver will be used instead. To configure a different rate limiting strategy, go to "GitHub API usage" under "Configure System" in the Jenkins settings.

Something which is also weird is that 2 webhooks were received triggering the examination twice, but maybe that is another problem. Is this something by design? I mean does jenkins really need to check the tags? If yes, maybe this could be configurable?

 

UPDATE: reopening the PR also triggers the tags examination
