[jhoshiko]

Added a dockerfile and a docker compose file for building a docker container that can build yocto images. Included yocto release files that are unzipped when building the docker container.

@couryrr-afs @drmrd This PR has a simple dockerfile that is automated to build the yocto core-image-minimal target. You can edit this file to add steps for custom layers and change the target to another.

From running the oe-init-build-env script:

You can now run 'bitbake <target>'

Common targets are:
    core-image-minimal
    core-image-full-cmdline
    core-image-sato
    core-image-weston
    meta-toolchain
    meta-ide-support

I built the dockerfile following the steps found here, which I would recommend referring to when you edit the dockerfile.
