Merge TestOnlyLocalExternalIPs, TestOnlyLocalLoadBalancing, and TestOnlyLocalNodePorts together into TestExternalTrafficPolicyLocal. Drop the assertIPTablesRulesEqual tests in favor of runPacketFlowTests. Remove TestOnlyLocalNodePortsNoClusterCIDR; the relevant bits of the "no local detector" case are already fully covered by TestInternalExternalMasquerade.
