Update dependencies

[cutler-scott-newrelic]

Summary

A lot of the dependencies are now majorly out of date, but simply changing the cargo.toml is not enough, a fair amount of code will need to be re-written to support the newer libraries.

Additional context

Updating libraries will support newer features and hopefully improve performance.

Hello, I would like to work on this issue.
It will be my first time contributing to open source project, do you have any advice?
I will make a commit per dependency update, is it a good way?

I am using rusty hog at work (I am a computer science student and apprentice at Amadeus), I like it and want to help.

I would be happy to try to update it to gitoxide too, but I will try this issue first.
I forked the repo and I started to work on this issue and I will keep you updated.
Feel free to share any advice!
Thanks

Hi Coruscant, thanks for the offer! I would definitely recommend to start with one package at a time, and avoid a few of the more problematic packages by focusing on the best maintained ones like Clap

Also, avoiding the packages that are actually making network calls will probably help keep things simple

Okay! I will try to start with clap then. Thanks
