* Updating Cosmos DB to the latest driver and removing flags for
features that are no longer used.  For examply myid was needed
when id only supported hash lookup.  Now id supports range index
so scan can be handled.

* Updating version

fixing a bug in update.

* Adding Azure Cosmos Driver.
Still some improvements to make like automatically creating the YCSB database and usertable collection. But this does bring in the all the latest SDKs / etc.
