[test] Add tests for ACM prefer feature, adjust logging

[scott-brust]

Problem

ACM related interfaces/features done have test coverage, we should add tests.

Solution

• Test Network prefer() behavior
  • Test 2: When multiple networks are available, the one that is prefered should be used for the cloud connection
  • Test 3: Only one network can be preferred at at ime
  • Test 4: When multiple networks are available, and the cloud connection is on one, if the other is preferred, the cloud connection should move to that one as soon as possible
  • Test 5: If one network is available, and the unavailable network is preferred, if the preferred network becomes available, the cloud connection should move to that one as soon as possible
  • Test 6: If multiple networks are available, and the network being used for the cloud connection goes down, the cloud connection should be disconnected and reconnected immediately on the next best available network

Most of these tests only apply to the MSOM platform
