Gentoo Build Publisher: Getting failure logs

When one is performing Gentoo builds inside a CI/CD container (inside another container) and a build fails it is sometimes desirable to create a bug report at bugs.gentoo.org. Often the Gentoo developers require that you include the error output and build logs. However getting the logs out of the container can be tedious. For my builds I've added a step which gathers the Jenkins build output, portage build.log file(s) and emerge --info output and attaches them to an email so that they can be used in bug reports.
