Fix issues with WcfLogReceiverClient - alternative

[304NotModified]

More backwardscompatible to v4. Both one and two way are now unit tested with a ServiceHost

Keep the facade idea, but a bit different

• WcfLogReceiverClient is renamed to WcfLogReceiverOneWayClient. We have now WcfLogReceiverOneWayClient and WcfLogReceiverTwoWayClient. Both will implement the same (new) interface.
• WcfLogReceiverClientFacade is renamed to WcfLogReceiverClient
• WcfLogReceiverClient (the facade) now delegates (almost) everything of WcfLogReceiverOneWayClient/WcfLogReceiverTwoWayClient.
• WcfLogReceiverClient has a Proxy property, if still something is missing (cast is probably required for the end-user)

Things to think about:

• ILogReceiverClient is renamed to ILogReceiverOneWayClient. This is not needed, maybe revert it. (there are already some inconsistent namings to bad)
• The WcfLogReceiverOneWayClient and WcfLogReceiverTwoWayClient does contain code duplication due to the ClientBase inheritance. Difficult to solve with delegates. Maybe fix with T4.

TODO

• re-enable the warnings as error, and fix the xmldocs
• enable cookiecontainer

• compare code with NLog 3.2.1
• revert ILogReceiverClient is renamed to ILogReceiverOneWayClient ?

ILogReceiverClient.cs - Breaks compatibility because it doesn't have any of the methods from 3.2.1
WcfLogReceiverClient.cs - No longer inherits from Clientbase.
WcfLogReceiverOneWayClient.cs - is equivalent to WcfLogReceiver in 3.2.1

For better backwards compatibility to 3.2.1:

• Keep methods and attributes 3.2.1 in ILogReceiverClient
• Keep WcfLogReceiverClient using ILogReceiverClient, but mark as deprecated, so that we can clean up and move people to ILogReceiverOneWayClient/ILogReceiverTwoWayClient

For better backwards compatibility to 4.0.1:

• Keep methods and attributes in ILogReceiverOneWayClient

For TwoWay Client:

• Duplicate ILogReceiverOneWayClient, but make it replace OneWay with TwoWay

Long Term Suggestions:

• As already suggested, use T4 template to generate ILogReceiverClient, ILogReceiverOneWayClient, and ILogReceiverTwoWayClient
• As already suggested, use T4 template to generate LogReceiverClients
