Change (cmd): Revert images to use CMD /bin/sh and /bin/bash (#16)

Setting `CMD` values to `ansible` is mostly pointless as `ansible` is an executable rather than a shell. Parameters specified after the `docker run image:tag` command are ignored unless `ansible` is set as the images' `ENTRYPOINT`. Yet since `ansible-playbook` is most likely to be used in images, specifying `ansible` as the images' `ENTRYPOINT` would introduce a breaking-change in design of the images potentially reducing their usefulness by being too specific in design. Having a more generic design is preferred and allows administrators to also interact within container shell environments for administrating systems in combination with `ansible` binaries.

This reverts commit 862bf05.
