[JENKINS-57516] - Support tag creation on tag push

[sheldonrong]

Able to detect a tag creation from the Bitbucket PushHead Event and automatically create tags in Jenkins. This allows the workflow to build projects when tagging and/or pushing a commit.

This changeset adds a tag detection branch logic in the NativeServerPushHookProcessor.HeadEvent's heads function.

Setup Bitbucket server and jenkins server using docker container, and is able to verify that the tags can be instantly created once dev ran git push --tags using their git command line inside a repo.

@Casz Thanks for reminding, updated the commit, and should be good now :)

@Casz looks like the continuous-integration/jenkins/pr-merge is stuck :)

[sheldonrong]

@Casz any updates on this one?

Great if someone could push this forward. This is the only feature missing for us in our current CI/CD pipeline :)

Thx Joseph. Will test it as soon as I can :)

[darxriggs]

A test covering this new logic would be more than welcome.

Verified that this works. Thanks a lot. Hopefully I can provide a PR for tag delete events :)

Hoping someone can see this and respond -- it seems like this fixed an issue where once the Webhook was setup in Bitbucket to notify on Tag Created events, this was needed to process the event notification... Am I missing something, or is there still not logic to automatically include Tag Created as an option when automatically registering the webhook when the job is created...
