proxy/iptables: Add more stuff to the unit test
The external traffic policy terminating endpoints test was testing LoadBalancer functionality against a NodePort service with no nodePorts (or loadBalancer IPs). It managed to test what it wanted to test, but it's kind of dubious (and we probably _shouldn't_ have been generating the rules it was looking for since there was no way to actually reach the XLB chains). So fix that. Also make the terminating endpoints test use session affinity, to add more testing for that. Also, remove the multiple copies of the same identical Service that is used for all of the test cases in that test. Also add a "Cluster traffic policy and no source ranges" test to TestOverallIPTablesRulesWithMultipleServices since we weren't really testing either of those. Also add a test of --masquerade-all.
