Move to Azure.Data.Tables

Microsoft have been changing the base libraries used for storage accounts and this release moves the codebase to use Azure.Data.Tables instead of Microsoft.Azure.Cosmos.Table.

Update Azure Cosmos DB Table to 1.0.8

A change between Microsoft.Azure.Cosmos.Table version 1.0.7 and 1.0.8 caused an exception to be thrown when checking if a table exists when the newer version was added to code. This release updates the library to use the latest version 1.0.8 to stop the exception.
