After successful implementation of JENKINS-47891 (with https://github.com/jenkinsci/bitbucket-branch-source-plugin/pull/138) our Jenkins server can register the Native webhooks in repositories on a corporate Bitbucket Server.

In our case however, the Jenkins server is accessible to Bitbucket under a different URL than is used by consumers in our development lab (and which it announces via generated URLs through the string in global Jenkins configuration settings), so we would like to have an option in the config of the Bitbucket connector for a particular server of using a non-default Jenkins URL for webhooks managed by that connector instance.
