[Transaction] klay_estimateComputationCost
Generates and returns an estimate of how much computation cost will be spent to execute the transaction. Kaia limits the computation cost of a transaction to 100000000 currently not to take too much time by a single transaction. The transaction will not be added to the blockchain like klay_estimateGas

CallObject
object
The transaction call object. See the next table for the object's properties.
(optional) The address the transaction is sent from.
(optional when testing the deployment of a new contract) The address the transaction is directed to.
