gas limit had to be set when setting executors on base: kept getting UNPREDICTABLE_GAS_LIMIT error. It should definitely not cost more than 100000 gas to set limit... but this may be a problem on other chains in the future.
Also update executors.json with uniswap v2 address on mainnet --- don't change below this line --- ENG-4101 Took 22 minutes Took 7 seconds
Added a roles.json file where we can define all the addresses that need roles --- don't change below this line --- ENG-4101 Took 42 seconds
