Implement all and -A options to relevant commands

[yokaze]

Motivation

Currently, several commands lack an option to list all the pods and namespaces.
For example:

• npv dump, npv inspect, and npv list: requires a pod name
• npv id: requires a namespace name

It is beneficial to list everything with an appropriate option.

How

• all can be used instead of a pod name
• -A or --all-namespaces can be used instead of a namespace name
• Additional name or namespace lane will appear only when these flags are specified

Checklist

• Finish implementation of the issue
• Test all functions
• Have enough logs to trace activities
• Notify developers of necessary actions
