Account aliases (for recovery?)

[s8sato]

Feature request

2. Open a separate issue to discuss whether we want to implement alias as part of Iroha or delegate this to external service (I would prefer to keep alias resolution as a separate service outside Iroha to not complicate the codebase)

Motivation

As long as transaction.payload.authority is AccountId, aliases should be resolved before the transaction building.
Otherwise the transaction signature will be affected by aliases, which means verifiers should consider alias history of the transaction authority

you make a good point for the case of having alias resolution as external service
