ClickHouse java client - reusing same instance of ClickHouseClient gives execution timeout after 10 inserts

I am new using clickhouse and I have assembled a project in java using java client.

```xml

com.clickhouse
clickhouse-http-client
0.6.0

org.apache.httpcomponents.client5
httpclient5
5.2.1

```

```java
HashMap options = new HashMap<>();
options.put("user", "user");
options.put("password", "pass");

String url = "my-clickhouse-host";
ClickHouseNode server = ClickHouseNode.of(url, options);
ClickHouseRequest read = ClickHouseClient.builder()
.nodeSelector(ClickHouseNodeSelector.of(ClickHouseProtocol.HTTP))
.option(ClickHouseClientOption.SOCKET_KEEPALIVE, true)
.build()
.read(server).write();

for (int i = 0; i < 11; i++) {

String id = UUID.randomUUID().toString();
String field1 = "field1" + (i);
String field2 = "field2" + (i);
String field3 = "field3" + (i);
String field4 = "field4" + (i);

String query = String.format("INSERT INTO mytable VALUES ('%s', '%s', '%s', '%s', '%s')",
id,
field1,
field2,
field3,
field4);

read.format(ClickHouseFormat.CustomSeparated)
.query(query)
.executeAndWait();

}
```

This code only inserts 10 records, after that I get an Code: 159. Execution timed out Exception

I have already tried to change and add some ClickHouseClientOptions but I always get the same behaviour. How can I reuse the same client connections in clickhouse using java client?

Start with the Java reproduction in the issue, especially ClickHouseClient.builder(), the ClickHouseRequest setup, and the executeAndWait() loop using clickhouse-http-client 0.6.0. Reproduce the timeout after the tenth insert, then inspect the client and request lifecycle to determine whether the same connection can be reused. Done means repeated inserts complete without the Code 159 execution timeout.
