This commit adds support for OCI images. Most of the docker related code is reused for OCI classes and Docker classes have been refactored so now they are a splecialization of the OCI classes. It is done this way since KIWI internally only uses OCI format to operate with containers, therefore docker images just differ from OCI images by the way they are packaged or unpackaged.
