In case you do *not* want to automatically add the repository for the IBM service and productivity tools, set the following variable to `no`. Default is `yes`, meaning that the role will download and install the package specified in variable sap_hana_preconfigure_ibm_power_repo_url (see below) and also run the command /opt/ibm/lop/configure to accept the license.
The following variable is set to the location of package ibm-power-repo-lastest.noarch.rpm or a package with similar contents, as defined by variable __sap_hana_preconfigure_ibm_power_repo_url in vars/RedHat_7.yml and vars/RedHat_8.yml.
