Cosmos Azure and JanusGraph (cosmosdb_cell_level)

Hello all,

**Describe the feature:**

I am testing janusgraph with Azure cosmos DB version [cqlsh 5.0.1 | Cassandra 3.11.0 | CQL spec 3.4.4 | Native protocol v4] and I debugged some bugs to the point where I can't move forward anymore .

I am not really sure if this is a bug issue or a feature request. Please, feel free to change it.

Its possible to use Cosmos Azure and JanusGraph ?

**Describe a specific use case for the feature:**

The error is:

`Caused by: java.util.concurrent.ExecutionException: com.datastax.driver.core.exceptions.InvalidQueryException: Use

In which i can read `Please re-create the table with cosmosdb_cell_level_timestamp=true AND cosmosdb_cell_level_timestamp_to mbstones=true AND cosmosdb_cell_level_timetolive=true.` but i didnt find how to force janusgraph to add this AND clauses.

i arrived to this class https://github.com/JanusGraph/janusgraph/blob/master/janusgraph-cql/src/main/java/org/janusgraph/diskstorage/cql/CQLKeyColumnValueStore.java#L187

and i think when create tables It is mandatory to include these clauses how i see on https://github.com/Azure-Samples/cosmosdb-cassandra-kafka/blob/2cfba78e3c70dea5dd1fd771636d8db1978b7e1d/README.md#create-keyspace-tables-and-start-the-integration-pipeline

I could provide more logs if necessary

Thanks,

Start at janusgraph-cql/src/main/java/org/janusgraph/diskstorage/cql/CQLKeyColumnValueStore.java around line 187 and compare its table creation behavior with the Azure Cosmos Cassandra README. Determine whether JanusGraph can create tables with the required cosmosdb_cell_level_timestamp, tombstones, and timetolive clauses, and define support as resolving the reported InvalidQueryException.
