Exposed chunk RPC API (nearcore 0.4.2+)

Ref: near/nearcore#1524

LGTM, but please make sure CI passes

@vgrichina I expect it will pass once nearcore is deployed with the PR, so in theory, we only need to run CI once more once that happens. I am just proactively creating PRs :)

Do you plan to wait until it is deployed on master testnet or on staging? If you only want to wait for staging deploy (or not wait at all), then it's necessary to gate this test by nearcore version.

I plan to wait for the API hit master. I hope it happens soon since without this API Explorer is useless (I cannot get a transactions list from nearcore otherwise).

@vgrichina The tests pass on the current (already deployed) master. Staging should work fine as well, though it is down at the moment. The CI deployed nodes needs to be updated to include the chunk API.
