[Feature]: Send all remaining balance of token to another account

[iramiller]

Summary

Send remaining account token balance to another account.

Problem Definition

In certain situations it makes sense to send the entirety of the remaining balance of a token from one account to another. Some example usages would be if a user wishes to migrate balances from one account to another or during ICA operations where a balance may need to be moved to another account without a separate expensive query for the balance first (c/o Sam Hart of skip.money ).

Proposal

Create a method that allows the entirety of an accounts token balance to be sent to another account. As the fees are annotated on the transaction up front, the remaining balance is all available to be transferred (per @alexanderbez ).

+1 what is currently the way to do this? Get the balance and subtract the gas fee? How can you be sure the gas fee will be what you expect?

[alexanderbez]

The current way is to (A) query the balance, (B) calculate and deduct fees and (C) send remainder. Such a proposal and implementation would omit the need for (A) and (B), thus making it a one step process. I.e. no queries and no balance calculation needed.
