Description:
The RPM package service description sets the deprecated --logging.dest flag which causes the following problems:

1. Kibana generates a deprecation warning which users are unable to resolve
   @mshustov suggested setting deprecation.skip_deprecated_settings='logging.dest' to suppress the warning
2. RPM package keeps writing to rotated log files when using the new logging configuration
   When using the RPM package and the new logging configuration, Kibana will keep writing legacy request logs to log files that have already been rotated (exceeded size or interval duration).

This is because legacy logging is enabled in the service description by setting --logging.dest=
