Suspicious pods

Suspicious pods is a very simple tool, which does a very simple task: print a list of pods in your Kubernetes cluster that might not be working correctly, along with a reason on why that pod is considered suspicious.

Example:

$ suspicious-pods -- help
suspicious-pods 0.4
Prints a list of k8s pods that might not be working correctly

USAGE:
    suspicious-pods.exe <namespace> --format <format>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -f, --format <format>    The output format. Valid values are: text, markdown [default: text]

ARGS:
    <namespace>    The namespace you want to scan [default: default]
    
$ suspicious-pods

This is useful in big deployments, when you have a large number of pods and you just want to get a quick glimpse of what might be failing in your cluster.
