Add xpk inspector

[Obliviour]

Features

python3 $XPK inspector ... prints out debug information related to kueue, jobset, workload, gke cluster , gke node pools, and cloud console. It exports all the info needed to debug workload failures to a file to debug with.

• Prints out Cloud console links to quota page, iam permission page, gke cluster, workload, all workloads
• Set the --workload flag when interested in why a specific workload is not working
• Run without the workload flag to investigate general health of the gke cluster and workload management such as node pool health
• set the --print-to-terminal arg to print details to console.

Users can investigate the lawyer file and also share the lawyer file with experts to quickly allow investigations to uncover failures.
