check_rancher2

This release adds performance data on a single cluster check and fixes the "project" check. Inlcudes PR #20 and #22 .

Potential breaking change: Replace jshon command with jq, allowing to use filtering in json content. jq is more widely used than jshon and has helpful features such as filtering (search). This is used to fix issue #19.

Make sure you have jq installed on your system where you run check_rancher2.

This release enhances the plugin to check for workloads in a specific namespace. This is necessary when there are multiple workloads with the same name around (for example "nginx") but deployed across multiple namespaces.

This also fixes the pod check which already was prepared to check for pods in namespaces (according to documentation) but was missing to read the namespace given with -n namespace.
