sap_hana_preconfigure/SLES: sap_hana_preconfigure_update needs validation/wait

[marcelmamula]

Issue

Running sap_hana_preconfigure with sap_hana_preconfigure_update can cause significant changes to OS, resulting in longer kernel patch/upgrade process. This will result in failing sap_install_media_detect role when attempting to execute package module, while kernel is still being worked on.

Post-reboot patching visible in process list:

root      1163   950  0 13:10 ?        00:00:00 /usr/bin/python3 /usr/lib/zypp/plugins/commit/zyppnotify
root       950     1  0 13:10 ?        00:00:00 /usr/bin/zypper -n purge-kernels
root      1067     1  0 13:10 ?        00:00:00 gpg-agent --homedir /var/tmp/zypp.Hik3c0/zypp-trusted-krHyD8o2 --use-standard-socket --daemon

Error during sap_install_media_detect execution, when unzip was supposed to install.

Solution proposal

1. Validation in sap_hana_preconfigure to ensure that package operations are completed, before ending role.
