Get Temporary key(nonce) for ganerate transaction(ex Transfer, Dapp Create or Token Create)

get

• By using the signature value recorded in the transaction, the key value is obtained to prevent duplicate calls by other users.
• In the existing blockchain, the nonce value is a serial number that means the number of TX occurrences, but in Metacoin, it is a random key value.
• This command replaces the existing "getkey" API.
