"""Test rescan behavior of importaddress, importpubkey, importprivkey, and
importmulti RPCs with different types of keys and rescan options.
In the first part of the test, node 0 creates an address for each type of
import RPC call and sends BTC to it. Then other nodes import the addresses,
and the test makes listtransactions and getbalance calls to confirm that the
importing node either did or did not execute rescans picking up the send
transactions.
In the second part of the test, node 0 sends more BTC to each address, and the
test makes more listtransactions and getbalance calls to confirm that the
importing nodes pick up the new transactions regardless of whether rescans
happened previously.
