[Qualify of Life] Support better CLI usage on the debug server

[blu-dev]

QoL suggestion

Support better CLI usage on the debug server.

Is your suggestion related to a usage problem? Please explain.

The debug server (which allows querying information from loaded tables) should support a better system for getting CLI args and also for the end user.

How could we make this better?

It shouldn't panic on an empty message (not sure if this is still the case?) and it should print out how to use a command.

The preferrable method of doing this is with StructOpt/clap.

Is there an alternative way of doing things you'd like to suggest?
