Move whether the package or source install type is enabled out of the source-repositories element and into the base element. source-repositories wasn't a great fit for this functionality to begin with. Specify the install type for an element via the DIB_INSTALLTYPE_<install_dir_prefix> environment variable. Additionally with this approach, any new install type can be added in an element, without having to update source-repositories or anything in dib. You could just write your install type implementation under nova-foo-install, then define DIB_INSTALLTYPE_nova=foo in your environment, and the scripts under nova-foo-install would get run during the image build. Source installs (any scripts under <install_dir_prefix>-source-install) is the default install type for all elements. Change-Id: I9414aca360c41e030e27d3d0c0a52d9d8e13d8b1
