We rely on MT-SRE / SRE-P automation to create some secrets and config maps for us during the installation process. We need  to update the odh-deployer script to account for issues with some of these secrets (i.e the secret not being created).

There are probably multiple options for this, but I think the safest option is for installation to fail. Missing secrets can result in issues like the monitoring stack failing to come up, which qualify as a failed RHODS installation.
