create alias key: allow to generate or import a private key, and encyrpt with the same ecdsa password of operator key
declare alias key for the operator: bind the alias public key address to the operator (ecdsa public key) hold in AP Contract
Later on, whenever we signed, we can look up the APCOnfig contract
The operator is implemented to also check and make sure there is an alias <-> operator binding existed if the ecdsa singer key doesn't match operator address.
Implement alias key concept as following:
