LogReceiverWebServiceTarget backwards compatible problem

[tryhp3]

After the update (to NLog 4.0) I have a serious problem:

1. 'NLog.CustomExtendedService.LogReceiverSecureService.CreateWcfLogReceiverClient()': return type must be 'NLog.LogReceiverService.WcfLogReceiverClientFacade' to match overridden member 'NLog.Targets.LogReceiverWebServiceTarget.CreateWcfLogReceiverClient()'
2. New class WcfLogReceiverClientFacade does not include: ClientCredentials and Endpoint.

Hi,

• I don't fully understand the problem of point 1. Yes it is a breaking change, but what is the serious problem?
• There is an endpoint address in the LogReceiverWebServiceTarget. Could that help?

PS: I noticed that WcfLogReceiverClientFacade is a mess and should be refactored. See #784

I see the problem:

• WcfLogReceiverClientFacade won't inherit from ClientBase<...>. But in 3.2.0 WcfLogReceiverClient was returned, and this class did implement ClientBase<...> (which contains 'EndpointandClientCredentailsproperties). Thus: WcfLogReceiverClientFacade should inherit fromClientBase<..>`. But this is difficult to fix. We have to find a good solution for this.

This is unwanted breaking change from #565 (it was claimed to be backwards-compatible)
