The goal of this make sure that test code is correctly organized to ensure that test suites aren't dependent on each other.
* UnitTests get their own project now (renaming Microsoft.SqlTools.ServiceLayer.Test to Microsoft.SqlTools.ServiceLayer.UnitTests) which is about 90% of the changes to the files.
* IntegrationTests no longer depends on UnitTests, only Test.Common
* Any shared components from TestObjects that spins up a "live" connection has been moved to IntegrationTests Utility/LiveConnectionHelper.cs
* The dictionary-based mock file stream factory has been moved to Test.Common since it is used by UnitTests and IntegrationTests
* Added a overload that doesn't take a dictionary for when we don't care about monitoring the storage (about 90% of the time)
* The RunIf* wrapper methods have been moved to Test.Common
* OwnerUri and StandardQuery constants have been moved to Test.Common Constants file
* Updating to latest SDK version available at https://www.microsoft.com/net/core#windowscmd
* Moving unit tests to unit test folder
* Changing namespaces to UnitTests
* Moving some constants and shared functionality into common project, making the UnitTests reference it
* Unit tests are working!
* Integration tests are working
* Updating automated test runs
* Fixing one last broken unit test
* Exposing internals for other projects
* Moving edit data tests to UnitTest project
* Applying refactor fixes to unit tests
* Fixing flaky test that wasn't awaiting completion
