Performance data not compliant with monitoring-plugin API specification

[moschi]

The current performance data units of measurement are not compliant with the monitoring-plugin API performance data section specified under https://www.monitoring-plugins.org/doc/guidelines.html#AEN201 .
This can create problems with monitoring systems that strictly implement this specification (such as icinga2) since they then ignore the 'malformed' performance data results.

Possibly a parameter to enforce strict monitoring-plugin API compliance would be a solution?

The plugin worked perfectly for years for us and others. Feel free to submit a pr..
