[Feature Request] configurable getEthPriceUsd

[clouds56]

It would take long getEthPriceUsd when I'd like to deploy to my local network (and for every single transaction).
Is it possible

1. disable getEthPriceUsd via config
2. cache the result in a single deployment
3. pass custom getEthPriceUsd function

Hey, thanks for the feature request - it makes 100% sense.
We're currently focused on other projects, but if you're willing to work on a PR for this I'd be happy to assist.
