Test: Reorg. cord-tester code in general.
Change test cases to use olt configuration as appropriate when switch isn't running in the test container.
Remove olt multitable config and fold into olt_config.
Rename subscriberMultiTable to cordSubscriber test.
Change the eval script to reflect the new changes/design in cord tester.
