Pickup some commits not related to Mono from #374 (#410)

* Add some missing method to LoggingHandler

* Avoid to alloc an huge error message when the test not failed.

* Update the unittest

* Update Microsoft.NET.Test.Sdk from 15.0.0 to 15.7.2, fix that unable to debug an unittest for the second time.
* Disable parallelization for InternalLoggerFactoryTest.TestMockReturned to avoid an rare test failure.
* Remove `dotnet-xunit` since it's never used and will be discontinued, see https://xunit.github.io/releases/2.4-beta2

* Remove space from filename

* Switch back to `DiscardSomeReadBytes` since it's avaliable

* Rework some logic in TlsHandler

* Make sure TlsHandler.MediationStream works well with different style of aync calls(Still not work for Mono, see #374)
* Rework some logic in #366, now always close TlsHandler.MediationStream in TlsHandler.HandleFailure since it's never exported.

* Workaround to fix issue 'microsoft/vstest#1129'.

* Change the default of TcpServerSocketChannel.Metadata.defaultMaxMessagesPerRead to 1
