Hardhat tasks can be refactored more...

[balajipachai]

I have gone through all the hardhat tasks and have observed there are a few lines in each task that can be refactored.
Those few lines are:

const privateKey = getPrivateKey();
const rpcProviderUrl = getProviderRpcUrl(blockchain);
const provider = new providers.JsonRpcProvider(rpcProviderUrl);
const wallet = new Wallet(privateKey);
const signer = wallet.connect(provider);

In some tasks the rpcProviderUrl is named as sourceRpcProviderUrl and provider is named as sourceProvider.

It is a matter of naming convention we can decide upon using only rpcProviderUrl and provider and refactor the above code into a function.

The function can either be called setup or accountAndNetworkSetup in a file namely setup.ts.

This file then can be imported in almost all hardhat tasks and the function will be invoked instead of using the redundant 5 lines.

What this will do?

• Improve code readability, thus making it easier to understand.
• Remove redundant lines, thus making the code concise and compact.

Please do let me know what you think about, if this sounds good, I can open a PR for the same.
