Checkmk Werk 10182: Cleanup version specific cache files during version updates

ID: 10182 Title: Cleanup version specific cache files during version updates Component: Core & setup Level: 1 Class: Bug fix Version: 1.7.0i1 In some cases it happened that some Checkmk version specific cache files, e.g. in <tt>tmp/check_mk/check_includes</tt> or <tt>var/check_mk/precompiled_checks</tt> were not updated after the update, making Checkmk use files of the previous version after the update. The <tt>cmk-update-config</tt> command, which is automatically executed by <tt>omd update</tt> during the version update, is now cleaning up these caches automatically to ensure a clean start with the new version.
