Description of problem:
=======================
In RHCS 6 we decided to continue the support for "--yes-i-know" flag[https://bugzilla.redhat.com/show_bug.cgi?id=2073030].

But in RHCS 8, when the flag is passed to the command, it fails with below error -

# cephadm --verbose --image registry-proxy.engineering.redhat.com/rh-osbs/rhceph:ceph-8.0-rhel-9-containers-candidate-34840-20240918232232 bootstrap --mon-ip 10.70.44.131 --registry-url subscription.rhsm.redhat.com:443 --registry-username qa --registry-password MTQj5t3n5K86p3gH --yes-i-know

gpgcheck=0
enabled=1



How reproducible:
=================
Always


Steps to Reproduce:
=================
1. Run cephadm bootstrap command with flag "--yes-i-know"
e.g.
cephadm bootstrap --cluster-network NETWORK_CIDR --mon-ip IP_ADDRESS --registry-url registry.redhat.io --registry-username USER_NAME --registry-password PASSWORD --yes-i-know


Actual results:
===============
Bootstrap command fails with "unrecognized arguments: --yes-i-know" error.


Expected results:
===============
Command should be successful.


Additional info:
===============

Flag is NOT supported in RHCS 8.0 and RHCS 7 as well.
