DRIVERS-2583: Drivers should detect Cosmos and DocumentDB servers by examining host names added to a topology during MongoClient construction. If SRV is used, this check should be done on the SRV URI's `{hostname}.{domainname}` prior to SRV lookup (ex: xyz.mongodb.net). If one or more host names end with ".cosmos.azure.com" (case-insensitive), log the following message using an "info" level: You appear to be connected to a CosmosDB cluster. For more information regarding feature compatibility and support please visit https://www.mongodb.com/supportability/cosmosdb If one or more host names end with ".docdb.amazonaws.com" or ".docdb-elastic.amazonaws.com" (case-insensitive), log the following message using an "info" level: You appear to be connected to a DocumentDB cluster. For more information regarding feature compatibility and support please visit https://www.mongodb.com/supportability/documentdb Drivers should not emit more than one log message per MongoClient construction. Note: there are no spec/prose tests for this ticket. Each driver should implement its own set of tests for this behavior. The libmongoc tests from mongodb/mongo-c-driver#1374 may be used as a reference. Note#2: Refer to DRIVERS-2753 if using standardized logging.
