[Transaction] klay_signTransaction

Constructs a transaction with given parameters and signs the transaction with a sender's private key. This method can be used either to generate a sender signature or to make a final raw transaction that is ready to submit to Klaytn network.

klay_signTransaction 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 klay_signTransaction.
