changed names and import paths for moving the repo; removed git
submodule init in puppet due to a bug in git 1.7.9 that uses abs path in
config of submodules. removing submodule init from puppet transfers the
responsibility of init submodules from vm to host, i.e. user would need
to clone recursively or init submodules manually.
raplace precise64 with raring64 for VM; bring submodule init back to pupet file;
add Dockerfile and Vagrantfile to spin up agent endpoint
