Bug description

Hello, after upgrading from linuxfabrik-monitoring-plugins versions 1.2.0.11-1 to v2.1.1, the redis-sensor check stopped working. Running it results in the following error:

Traceback (most recent call last):
  File "/usr/lib64/nagios/plugins/./redfish-sensor", line 273, in 'module'
    main()
  File "/usr/lib64/nagios/plugins/./redfish-sensor", line 209, in main
    sensor_data_value_state = lib.redfish.get_sensor_state(sensor_data, 'Reading')

This seem to have been introduced in linuxfabrik-monitoring-plugins version 2.0.0-1. Downgrading to 1.2.0.11-1 solves this issue. Thank you!
