Wrong URLs being rendered in grub2.cfg, menu.lst and default on all external smart proxies

Support

Problem:
PXE templates are being rendered with “foreman.domain.com” on all external smart proxies which causes systems to fail provisioning. Manual modification to grub2.cfg, menu.lst and default are overridden every time PXE default templates are built.

Expected outcome:
When building PXE default templates, URLs should reflect the hostname and ports specific to the smart proxy they are rendered on (i.e. proxy.domain.com:8000)

Foreman and Proxy versions:
Foreman 3.0
Katello 4.2

Distribution and version:
Rocky Linux 8.5
