Query nft coin commitments in the exchange module

[rgipson-figure]

Summary

Requesting a way to query if an nft coin is committed to a market in the exchange module.

Problem Definition

There currently isn't a way to query if an nft coin has been committed to a market.

The closest query options available are getaccountcommitments and getholds, but it will return all the coins for the account.

Our use case is our loan onboarding process will commit a loan nft to a market and confirm it is in the market before proceeding with the next onboarding steps. Our other services will also need the ability to check the commitment status of a loan for warehousing the loan.

Proposal

Options:

1. Add an optional query param of denom: string in getaccountcommitments
2. Add an optional query param of denom: string in getholds

Up for discussing other options or best practices for this use case.
