Implement full support for CosmosDB

[PalmEmanuel]

CosmosDB in Azure Tables flavor is supported in the SDK, but the connection strings build within the module assumes we're working with a storage account. A -TableType parameter or similar could be useful on the commands.

The -ConnectionString works right now, in the format of DefaultEndpointsProtocol=https;AccountName=<name>;AccountKey=<key>;TableEndpoint=https://<name>.table.cosmos.azure.com:443/;.
