Few days back when bugs.webkit.org went down for some time, some of the EWS builds failed with an exception while checking bug/patch status from bugs.webkit.org. e.g.: https://ews-build.webkit.org/#/builders/45/builds/3283, https://ews-build.webkit.org/#/builders/60/builds/915 EWS should gracefully handle the situation when bugs.webkit.org is down, and keep working. EWS builds do not need to talk to bugs.webkit.org to run the builds (buildbot already have a copy of the patch). The validate-patch step talks to Bugzilla only for efficiency purposes (to check if the bugs/patch is closed/obsolete/r- etc, and EWS can stop processing it).

This helped today. When Bugzilla went down, EWS builds didn't fail and kept working. e.g.: validate-patch gracefully handled Bugzilla being down in https://ews-build.webkit.org/#/builders/51/builds/15957
