[Account] eth_sign

The sign method calculates a Klaytn-specific signature with:

sign(keccak256("\x19Klaytn Signed Message:\n" + len(message) + message)))

Adding a prefix to the message makes the calculated signature recognizable as a Klaytn-specific signature. This prevents misuse where a malicious dApp signs arbitrary data (e.g. transaction) and uses the signature for impersonation.

eth_sign will be failed to baobab/cypress network because it is signed in the EN node, which means that the EN must have the key that you want to sign with. Steps to test eth_sign.
