Expand CM (Configuration Management) family coverage

Add 13 unmapped rules to CM family controls across rhel8, rhel9, and rhel10.
Focused on bootloader security and disabling unnecessary services/packages
for least functionality.

Changes:

CM-6 (Configuration Settings):
- Added GRUB2 password protection: grub2_password, grub2_uefi_password
- Added GRUB2 file permissions: file_groupowner_boot_grub2,
  file_owner_boot_grub2, file_permissions_boot_grub2
Total: 35 rules (5 new per product)

CM-7 (Least Functionality):
- Added service disablement: service_apport_disabled, service_cockpit_disabled,
  service_oddjobd_disabled, service_quota_nld_disabled, service_dhcpd_disabled,
  service_dnsmasq_disabled
- Added package removal: package_nis_removed, package_telnetd_removed
Total: 54-61 rules (6-7 new per product)

CM-7 already had significant coverage from previous mappings. These additions
focus on services that provide unnecessary network functionality or legacy
protocols that increase attack surface.

Total new mappings: 35 (across 3 products)
