Flaky tests: CreatingWritingDeletingCreatingFileWillReload et al

[Ryan Brandenburg]

These tests have recently taken to failing on OSx: http://aspnetci/project.html?projectId=XPlat&buildTypeId=XPlat_Mac_MacUniverseCoreCLR&tab=testDetails&testNameId=3759396832575739260&order=START_DATE_DESC&branch_XPlat=__all_branches__&itemsCount=50

Offending tests include:

• FileWatcherTests.MultipleFiles(usePolling: False)
• ConfigurationTests.CreatingWritingDeletingCreatingFileWillReload
• ConfigurationTests.TouchingFileWillReload

So the config tests will definitely fail if the file watcher functional tests are faling too:
