Task/fuzzylemma/gauge v4 deploy

[fuzzylemma]

I used the following dummy contract:

// SPDX-License-Identifier: MIT

pragma solidity ^0.6.7;

contract GaugeV4 {

  constructor(address[] memory _rewardTokens, uint256[] memory _rewardRates, address _governance) public 
  {  }

}

Contents:

• generalized hardhat deployment
• example/template deployment (only used real values for governance address)
  • template can be deployed with npx hardhat deploy --network hardhat --tags ex-gauge

Looks good
