(maint) Stop notifying haus on new release tickets

The jira text of one of the release tickets mentions haus by
[~matthaus], which creates a jira notification for any set of release
tickets created by this process. This is undesirable. This commit
updates the text to just reference Haus instead.

(CPR-59) Move git utilities into library

This commit goes through and takes all of the git based utilities in
00_utils.rake and moves them to their own ruby file in packaging. It
also goes through and finds every use of the old version and replaces it
with the new one. Finally it deprecates the old one so as to show a
warning message in the event the old one is still used. However it won't
break, just warn.
