* Implement a framework for having common code for release scripts
* Release scripts will go through hacking/build-ansible. build-ansible is
a pluggable script which will set a directory that has common code for
non-enduser scripts. It will then invoke the plugin which implements
that subcommand. Uses straight.plugin for loading each sub-command.
* We're going to add tools which are needed to test ansible (the changelog
generation, for instance) so we need to include the pieces relevant to
that in the tarball.
* Add straight.plugin to the sanity test requirements for the same
reason
* Skip compile test just for build-ansible plugins which won't be run as
part of sanity tests.
Announcements taken from https://github.com/ansible/community/wiki/RelEng:-ReleaseProcess
and then cleaned up:
* Update issue reporting blurb from feedback from acozine and gundalow
* Add a subject and to line for email output
* Ignore long line tests on the jinja templates (as jinja doesn't give
enough control to get rid of newlines when text wrapping)
* Skip shebang and compile tests for older pythons since this is a
release engineer-only script. (ok'd by mattclay)
