/**
 * A transaction to create a new node in the network address book.
 * The transaction, once complete, enables a new consensus node
 * to join the network, and requires governing council authorization.
 * <p>
 * This transaction body SHALL be considered a "privileged transaction".
 * <p>
 *
 * - MUST be signed by the governing council.
 * - MUST be signed by the `Key` assigned to the
 *   `admin_key` field.
 * - The newly created node information SHALL be added to the network address
 *   book information in the network state.
 * - The new entry SHALL be created in "state" but SHALL NOT participate in
 *   network consensus and SHALL NOT be present in network "configuration"
 *   until the next "upgrade" transaction (as noted below).
 * - All new address book entries SHALL be added to the active network
 *   configuration during the next `freeze` transaction with the field
 *   `freeze_type` set to `PREPARE_UPGRADE`.
 *
 * ### Record Stream Effects
 * Upon completion the newly assigned `node_id` SHALL be in the transaction
 * receipt.
