1.8.0

Version 1.8.0 adds a lot of additional performance data to the plugin. The cluster and node performance data now show more information, including percentages of resources used (for example CPU used in percent).
The plugin now also supports long parameters (-H and --apihost).
Additional parameters were added to specifically trigger alerts when certain performance thresholds are reached on a node or cluster level: CPU Usage, Memory Usage or Pod Usage.
Kudos and credits to @steffeneichler for this large PR!
