intermittent unreliable contract deploys

[mshakeg]

Problem

Developers may want to deploy a number of contracts in a single execution. However, the relay fails intermittently when deploying multiple contracts in succession.

It seems more reliable when deploying smaller contracts than larger ones.

This is possibly a rate-limiting issue on the hashio relay. In which case it might be helpful to increase the default rate limits to accommodate such a requirement.

Solution

1. Checkout to the branch in this PR
2. Run the test:smc:testnet script i.e. npm run test:smc:testnet and observe that most if not all of the SillyMediumContracts are deployed.
3. Run the test:slc:testnet script i.e. npm run test:slc:testnet and observe that a fewer number of SillyLargeContracts are deployed successfully.

Note: Since it's an intermittent issue it's possible that no contract deploy may fail.
