[Feature]: More complete QueryConsumerValidators endpoint

[jtremback]

Summary

It would be nice to have a simple endpoint that would return all information about a validator on a given consumer chain. Right now I am iterating over the validator list and calling consumer_commission_rate, resulting in potentially hundreds of parallel requests to get information for one consumer chain.

Problem Definition

Method of doing multiple queries (hundreds) is more error prone on the frontend, and I'm worried it is going to put RPC nodes under unnecessary strain

Proposed Feature

Add any available information about a consumer validator to QueryConsumerValidators
