remove mgmt packagegroups

These packagegroups are an unnecessary level of indirection.

Prior, the image feature was implemented by a packagegroup.  The
packagegroup was defined to pull in a virtual.  The virtual could
then be either a single package or another packagegroup.

Just implement the feature with the virtual directly to avoid
nonsensical situations like:
feature <- pkggroup <- virtual <- pkggroup.
