We added the DIB_distro_DISTRIBUTION_MIRROR arguments with I92964b17ec3e47cf97e3a3091f054b2a205ac768 as a way that we could source a list of mirrors and then have the distro elements choose which one applied to them. However, this hasn't worked out to be so useful. The openstack-ci-mirrors element is working as a mirror setup script -- it translates the openstack CI mirror list variables into the generic "DIB_DISTRIBUTION_MIRROR" as appropriate for each distro's build. Also, it turns out there's other things that need to be done, such as turning off gpg checking, which mean the idea of "just export variables" hasn't turned out as valid ... you need actual code involved to get it right. AFAICT we never actually documented these, and they do not seem to be in use. They have caused considerable confusion when dealing with new platforms as we try to keep consistency. Remove them.

ubuntu-minimal
The ubuntu-minimal element uses debootstrap for
generating a minimal image. In contrast the ubuntu element
uses the cloud-image as the initial base.
By default this element creates the latest LTS release. The exact
setting can be found in the element's environment.d
directory in the variable DIB_RELEASE. If a different
release of Ubuntu should be created, the variable
DIB_RELEASE can be set appropriately.
