* Connect with different properties should actually change context
- Up to now, calling Connect for a previously-connected URI would disconnect, then reconnect ot the original (not new) target. WIth these changes we handle changes to database name or other key properties by updating the ConnectionInfo and connecting to the new target
- Some interesting scenarios are raised by our API, notably that an empty database name maps to the default DB (which we know nothing about). This limits the new feature such that only if the DB Name is specified, we'll change the connection. Hence 2 calls to an empty DB will not result in a DB change.
Additional changes:
- After discussion with Ben, we're simplifying the cancellation logic. He had made changes to support this, so the main update is that we dispose the token in the final block after its last use (hence avoiding a disposed exception) and clean up the number of Waits required since we already have async cancellation support
- Factored some logic such that the OnConnection callback isn't invoked until after we've updated the database name in the GetConnectionCompleteParams method. Again, this supports reporting the actual DB name instead of leaving it blank for default DB requests.
* PR comment fixes
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
