DeleteValidatorTransaction

Returns a serialized `delete_validator` transaction. The transaction fee will be paid from the validator deposit that is being returned. Note in order for this transaction to be accepted fee + value should be equal to the validator deposit, which is not a fixed value: Failed delete validator transactions can diminish the validator deposit
