[JAVA] Try using Microsoft Azure SDK For SQL API of Azure Cosmos DB Service 4.6

Azure CosmosDB Java SDK version 4.x will be released in 2020.

The usage is published in the following document, but I tried to make what will happen as the minimum Hello World code. https://docs.microsoft.com/en-us/azure/cosmos-db/sql-api-sdk-java-v4

pom.xml

<!-- https://mvnrepository.com/artifact/com.azure/azure-cosmos -->
<dependency>
	<groupId>com.azure</groupId>
	<artifactId>azure-cosmos</artifactId>
	<version>4.6.0</version>
</dependency>

You can get the information you need to connect in the Azure portal.

package hello.cosmosdb;

import java.util.Iterator;

import com.azure.cosmos.CosmosClient;
import com.azure.cosmos.CosmosClientBuilder;
import com.azure.cosmos.CosmosContainer;
import com.azure.cosmos.CosmosDatabase;
import com.azure.cosmos.models.CosmosQueryRequestOptions;
import com.azure.cosmos.util.CosmosPagedIterable;
import com.fasterxml.jackson.databind.JsonNode;
