Reorganize the Tests for Testing Latest Net Native Tools + Last Stable Packages.

[shmao]

We wanted to use the tests added in GitHub to cover the case where the latest Net Native Tools are used with the last stable packages. To achieve that, we need to identify the tests that supposed to work in that scenario. https://github.com/dotnet/wcf/pull/1044 is an example of the change we need to do. We need to do such change for all the tests.

Scenario Tests

• [x] Binding
• [x] Client
• [x] Contract
• [x] Encoding
• [x] Extensibility
• [x] Security

Unit Tests

• [ ] System.ServiceModel.Duplex
• [ ] System.ServiceModel.Http
• [ ] System.ServiceModel.NetTcp
• [ ] System.ServiceModel.Primitives
• [ ] System.ServiceModel.Security

I've reorganized all the scenario tests. I tried making same changes for unit tests, but it turned out very few unit tests are really running in Tof right now because lots of unit tests are marked with [Theory] which is not recognized by Tof.

The plan is to make the changes for unit tests later when they can actually run. We can consider to move the issue to 'future' milestone.

Agree with your proposal. Thanks @shmao.
