src/script: add a script to help build ceph using containers

The build-with-container script tries to encapsulate nearly all major
build tasks using docker/podman containers. If there's no build image
locally it will create one for your. It provides targets for building
(make), testing (make check), building rpm packages or deb packages and
is designed to be fairly easily extended.
