New tool: pt-k8s-debug-collector provides information for support teams

This tool's purpose is to provide usable information for the support team to help understand and troubleshoot customer issues within the PXC Operator environment. Types of data collected should be the logs for the instance, a complete picture of the K8S objects related to that cluster, and the typical output expect of pt-mysql-summary for the underlying database instances.

It should be invoked by running:

pt-k8s-pxc-summary --namespace= --cluster=

Where the namespace is the K8S namespace that you should have set-context refer to, and the cluster is the name of the PerconaXtradbCluster object in Kubernetes.

There will be an analogous tool created for the PSMDB Operator as well (referenced in a separate ticket).
