Rebasing in container

rebase-helper can be run in Docker container. The package to be rebased has to be specified in PACKAGE environment variable. Alternatively, you can set REPOSITORY environment variable and point it to URL of any dist-git repository. In both cases, you can reference a specific branch, tag or commit by appending it to the package name or the repository URL:

$ docker run -it -e PACKAGE=foo#branch=f26 rebasehelper/rebase-helper:latest --outputtool json

Results of the rebase will be stored in an exported volume.
