#3260: gitlab webhook ignored if Git step uses https scheme

-------------------+-----------------------
 gitlab/github allow multiple access schemes.  We used https access at
 first with gitlab before we discovered how to configure deploy keys.  Then
 later when we switch from gitpoller to webhooks, we discovered changes
 were not triggering builds.  Evidently the scheme has to match;
 configuring buildbot to use the git@ scheme instead of the https: scheme
 solved the problem.

 This was with v0.8.8-1082-g1554b09, but I suspect it's also in current
 buildbot.

 Seems like it's at least worth documenting?
