        bugzilla-tool --help spews way too much text
        https://bugs.webkit.org/show_bug.cgi?id=31771

        * Scripts/bugzilla-tool:
         - Remove self.cached_scm initialization hack.
        * Scripts/modules/buildbot.py:
         - Make default_host accessible to callers.
        * Scripts/modules/commands/download.py:
         - Phrase help for all commands consistently and remove spurious help text punctuation.
        * Scripts/modules/commands/queries.py: Ditto.
        * Scripts/modules/commands/queues.py: Ditto.
        * Scripts/modules/commands/upload.py: Ditto.
        * Scripts/modules/multicommandtool.py:
         - Add HelpPrintingOptionParser.format_epilog to replace
           NonWrappingEpilogIndentedHelpFormatter and allow us to lazily initialize
           per-command help (thus removing the need for the cached_scm hack in BugzillaTool).
         - Make --help only show a list of commands like "svn help" and "git help" do --
           previously --help was listing all commands and options.
         - Sort list of commands alphabetically.
