ERC20BridgeSampler: Gas limits (#2405)

* `@0x/contracts-erc20-bridge-sampler`: Add gas limits to external quote calls. `@0x/contract-addresses`: Point `erc20BridgeSampler` to new version. * `@0x/contracts-utils`: Add kovan addresses to `DeploymentConstants`. `@0x/contract-addresses`: Add kovan `ERC20BridgeSampler` address. * `@0x/contracts-erc20-bridge-sampler`: Fix changelog. * `@0x/contracts-erc20-bridge-contracts`: Fix invalid CHANGELOG json (I hope).
