How important is this flag for Facilities ? I'm asking if it's something that the customer needs to be aware and it's highly relevante please add here as well -> https://github.com/ibm-mas/ansible-devops/blob/master/ibm/mas_devops/playbooks/mas_add_facilities.yml

Based on the flag, it will deploy the OM package in MREF. By default, this flag will be set to manual. The warning is just to inform them when they explictly change that flag's value to load-only or automatic, which will overwrite their changes.

By default, we always want them to use manual in production cases. The other values are used only in selected development environments.
