Setup RSA Key Setup with Snow CLI

[kameshsampath]

Description

As a developer I would like to setup the RSA keypair and add my public key to my Snowflake user. The PoC I did here https://github.com/kameshsampath/snow-builder-collection demonstrates the same via Docker container. It will be great to have the same add as snow command.

A possible nice to have is an update/new section to config.toml to allow the user start using the keys right away.

Context

Easy one command setup of RSA Keys with Public key added to the users RSA_PUBLIC_KEY with ease.
