images: add reference devtools container

includes container-base, and adds image features to make development
tools/headers available.
                                                                                                                                                                                                                                              Anything added to CORE_DEV_IMAGE_EXTRA_INSTALL will be installed into
the image in it's development variant.

The container shell is changed to bash from busybox.

package-management is added to this image type, but by default there
is no package feed configured (since it must be pointed at a build)
