Improvements to easy install

[revant]

• [ ] refactor code, improve nested code blocks, add sub-commands
• [ ] easy-install.py deploy, production setup, also migrate.
• [ ] easy-install.py develop, development setup
• [ ] easy-install.py build, build custom image
• [ ] easy-install.py wizard, interactive wizard, build and deploy, just deploy, create development setup, migrate existing setup.
• [ ] all options should also be picked up from environment variables if specified including SUBCOMMAND

Migrate part from deploy command and wizard needs previous project names, compose and env files. May need to store data under $HOME/.frappe/easy-install.

May explore curl -sSL https://frappe.fyi/easy-install | python3 if it works.
