Add loadable images support

This commit extends sle2docker to be able to load native docker
images. Current KIWI docker support builds loadable images, thus
they don't need to be build from a rootfs tarball any more. Image
RPMs for native images store the image tarball inside
/usr/share/suse-docker-images/native folder.

Related to bsc#1058371

This reverts commit 28fdfb1.
This commit introduced a regression, as the regex was including
'-docker' as part of the name in builds done with kiwi < 8. Also
this is no longer needed since kiwi-ng builds are handled in
native_images class, now this regex applies only for old builds.

Fixes bsc#1064010

* Improve metadata validation

This commit includes a couple of validations over the metadata file.
This way if something goes wrong with this data there is a better
error handling in proper feedback to the user.

Fixes#36

* Update tag-with-build flag for native images

This commit changes the behavior of the flag --tag-with-build
for native images. With the change it is possible to activate
multiple builds of the same image without having to deactivate them
in advance.

* Avoid shell calls in favor of Docker API

Fixes issue #39
