Gadget CLI

[shekohex]

Overview

• Added the Gadget CLI as a cargo subcommand.
• Implemented cargo gadget create to create a new blueprint and its gadget.
• Implemented cargo gadget deploy to deploy the blueprint to tangle network.
• added a way to automatically build and deploy the smart contracts for you.

Example

Checkout this PR branch, then do cargo install -p cargo-gadget --path .. Once installed, in a different terminal window/tab, try running cargo gadget create --name hello-world.

You will get a new blueprint from this template https://github.com/webb-tools/blueprint-template/ that contains everything you need to get started.

without any changes, try cargo build or even just go straight to cargo gadget deploy it should build everything for you if it is not built and deploy that to tangle. The command may fail, but following the error instructions should be good start. I did spent some time to write some good instructions when something bad happen to improve the DX.
