* fixed compilation of TCK

* upgraded to .NET Core 2.1 SDK

* removed restore stage - no longer needed

* bumpe tests to .NET Core 2.1

* Revert "bumpe tests to .NET Core 2.1"

This reverts commit f76e09f.

* workaround dotnet/msbuild#2275 until .NET Core 2.1 migration

* Revert "upgraded to .NET Core 2.1 SDK"

This reverts commit b000b76.

* improved test error result handling

* Revert "Revert "upgraded to .NET Core 2.1 SDK""

This reverts commit 1b1a836.

* Revert "Revert "bumpe tests to .NET Core 2.1""

This reverts commit 175d6ca.

* moving onto .NET Standard 2.0

* standardized most test projects

* fixed common.props references

* fixed .NET Core 2.1 build systems

* fixed issue with packing MNTR

* fixed issue with single test failure stopping build

* fixed failure handling

* fixed issues with Akka.Streams specs

* fixed scan for incremental tests

* working on FsCheck standardization issues

* removed more net implicit standard junk

* cleaning up implicit package versions; bumped to JSON.NET 12.0.1

* fixed port bindings for Akka.Cluster.Tools and Akka.Cluster.Sharding so suites could theoretically run in parallel

* fixed more ports

* fixed compilation errors

* rolled back to Newtonsoft.Json 9.0.1

* disabled parallelization in Akka.Streams.Tests

* added xunit.runner.json

* Disabled xunit.runner.json for Akka.Streams.Tests

* added more debug logging to scriptedtest

* issue appears to be the 1ms deadline not being long enough on .NET Core - stream isn't even wired up yet

* fixed race condition with Bug2640Spec for akkadotnet#2640

needed to give the system more messages to process so we guarantee hitting all four dispatcher threads when running the test suite in parallel.

* updated API approvals

* fixed issue with Bug2640Spec again

No longer looking for an exact thread count since the CPU may not schedule it that. Instead, just ensure that all of the threads hit on the dispatcher shut down when the dispatcher is terminated.

* same fix as previous
