Add a command to publish a crate on crates.io

This PR fixes #160

Thanks in advance for your review! :)

There are some linting issues.

We'll need to add the command to the docs on the wiki (https://github.com/mozilla/task-boot/wiki).

AFAIK Taskboot does not have cargo available in its path. Do you plan to add it in the Dockerfile ?

$ docker run --rm -it mozilla/taskboot cargo
docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"cargo\": executable file not found in $PATH": unknown.
