Tagger: Add SUSETagger to support SUSE-style detached changelogs
SUSE-style RPM packaging generally prefers having the RPM changelog detached from the main RPM spec file as a changes file. This file is typically named <pkg>.changes (corresponding to <pkg>.spec). At package build time in the Open Build Service, the content of the changes file is reformatted to the RPM changelog structure and appended to the spec file by the build system before rpmbuild processes it. This change adds support for this particular workflow, which is common in communities using an instance of the Open Build Service, such as (open)SUSE. This was originally authored by Michael Calmer. The code was ported to work on Python 3 and adapted for the current tito codebase by Neal Gompa. Co-authored-by: Michael Calmer <mc@suse.de> Co-authored-by: Neal Gompa <ngompa13@gmail.com>
