Hardhat Migration

[leovigna]

Add some documentation here about the features we should support.

• https://hardhat.org/guides/parallel-tests.html
• https://hardhat.org/hardhat-network/reference/#console-log
• https://mochajs.org/#-grep-regexp-g-regexp: Add to the readme on how to use grep regex to only run selective tests. Useful when in development and looking to only run some tests.

Consider scrapping the deploy.ts script generation and removing that in favor of some Hardhat solution. We should preserve the capability to create factory methods with Typechain for web3js, TruffleContract, ethers.
