enhance(os-other): Add 'part-scheme' support to RHEL 7 Kickstart
Adds part-scheme
template support to the base RHEL 7 kickstart. The part-scheme-default.tmpl
already supported RHEL 7 but it was not being called in the parent rhel-7.ks.tmpl
.
Tested with the default, and tested with a custom part-scheme template injection.
