Description of problem:

It has been identified that the satellite-installer utility is currently missing  the newly introduced parameter to enable iop. This could be a documentation bug, but it is not available in the current installer implementation.

--foreman-plugin-rh-cloud-enable-iop-advisor-engine

--reset-foreman-plugin-rh-cloud-enable-iop-advisor-engine

https://content-preview.docs.redhat.com/en/documentation/red_hat_satellite/6.18/html-single/release_notes/index#literal_satellite_installer_literal_parameters

The other parameter that is  mentioned in the installation document seems to be working fine:

1. satellite-installer --enable-iop

How reproducible:

Easily

Is this issue a regression from an earlier version:

No, this option was present in Satellite 6.17

Steps to Reproduce:

1. satellite-installer --foreman-plugin-rh-cloud-enable-iop-advisor-engine
   2025-08-19 00:02:40 [NOTICE] [root] Loading installer configuration. This will take some time.
   2025-08-19 00:02:42 [NOTICE] [root] Running installer with log based terminal output at level NOTICE.
   2025-08-19 00:02:42 [NOTICE] [root] Use -l to set the terminal output log level to ERROR, WARN, NOTICE, INFO, or DEBUG. See --full-help for definitions.
   ERROR: Unrecognised option '--foreman-plugin-rh-cloud-enable-iop-advisor-engine'

Actual behavior:

The parameters in Satellite 6.18 may have changed compared to 6.17, but these changes are not reflected in the documentation.

1. satellite-installer -h | grep -i iop
       --[no-]enable-iop                                                      Enable 'iop' puppet module (default: true)

Expected behavior:

1. satellite-installer --help | grep -i iop
       --foreman-plugin-rh-cloud-enable-iop-advisor-engine                    Enable iop-advisor-engine integration (current: true)
