The lsb_release command is required in order to run the playbook, because it uses ansible_lsb. Otherwise, the following error is raised:

fatal: [127.0.0.1]: FAILED! => {"msg": "The conditional check '(ansible_distribution == \"Ubuntu\" and ansible_distribution_version == \"20.04\") or (ansible_lsb.codename == \"kylin\" and ansible_lsb.major_release == \"v10\")' failed. The error was: error while evaluating conditional ((ansible_distribution == \"Ubuntu\" and ansible_distribution_version == \"20.04\") or (ansible_lsb.codename == \"kylin\" and ansible_lsb.major_release == \"v10\")): 'dict object' has no attribute 'codename'.

As the package containing lsb_release is different on different Linux distros, this commit only attempts to install it in SLE 16 SP6, where it is called lsb-release.
