env download does not mirror case files for ibm-cert-manager and ibm-licensing

[fketelaars]

Describe the bug
When running ./cp-deploy.sh env download, the required CASE files for the certificate manager and license server are not downloaded. During installation, the following error is issued:

TASK [utils : The following command will download the following CASE package: ibm-cert-manager 4.2.2. If you download the CASE package manually, wait for the download to complete before proceeding.] ***

Resolution
It turns out that OLM utils image-mirror subcommand does not download the case files, even if specified in the --components parameter. Looking at the documentation, it turns out that the installation expects that users run case-download first, which does take the 2 additional components into account.
