Community Provisioning Templates should be made Enterprise-grade
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1108864
Description of problem:
Community kickstart was renamed to "Satellite Kickstart Default for RHEL" in 1102276, but there are additional changes needed:
- proper rendering of trademark (Red Hat Enterprise Linux, because both RHEL & RedHat are not allowed AFAIK)
- remove mention of unspported RHEL versions (v. 4)
- remove the Fedora/CentOS template entirely (known as "Satellite Kickstart Default") - if users want to use community OS's, better to get the latest & greatest community template anyway
https://github.com/Katello/katello/pull/4240 should probably be merged first.
