Hi all,
I noticed that a 'TokenResolver' property is missing from CosmosDBConfig and for this reason is not possible to configure AsyncDocumentClient with this useful feature.

Having the chance to set a tokenResolver in configuration would help to develop long-running applications that follow strict policies about accessing CosmosDB collections (i.e. using a broker for resource tokens).

Is this feature planned to be added in next release of azure-cosmosdb-spark? If not, can I contribute to add this feature?

Thanks & Regards
