This PR fixes
rejoin_test_long_roundsto cause more expensive canister state cloning. The motivation for this change is that cloning many (100,000) canisters whose state does not change is cheap now that their canister state is wrapped in anArc. Hence, the updated test cycles through all those many canisters and keeps bumping their freezing threshold so that their canister state under anArcmust actually be cloned. The cyclic iteration is a busy computation and thus the original busy canisters with expensive heartbeats could be dropped now.
