When investigating a concurrency bug I had introduced in SqlEnvChange it was suggested that the DataAccessPerformance benchmarking project that I had been using could be transformed into a test to make sure coverage of continuous concurrent loading was covered in case similar issues are added again. This PR adds those tests.
There are two tests, one each for sync and async. Each tests will warmup for 1 second, execute for 60 seconds and create tasks over 4x the physical core count to ensure that there is contention. The data being read is from the sample Northwind database already used in the manual test project and is similar in shape and types to the Fortunes test of the original. The tests have been added in ProviderAgnostic\ReaderTest as TestConcurrentLoadSync and TestConcurrentLoadAsync because they can be re-used by other providers simply by changing the factory parameter.
