API refactoring: renaming `options` input arguments to `transaction`

[JeneaVranceanu]

What context is your feature request related to?

Refactoring of current API.

What solution would you like?

We have functions that accept CodableTransaction data type by the name options. The name is old which was left from the old days using TransactionOptions.

We must update the API by renaming options input arguments to transaction.

Any additional context?

It was the first point of #731
