Add support for ClickHouse JDBC driver in enum DatabaseDriver

[nosan]

#42799

I referred to the documentation here: https://clickhouse.com/docs/en/integrations/java/jdbc-driver. The documentation mentions the latest version as 0.6.5, but on their GitHub releases page (https://github.com/ClickHouse/clickhouse-java/releases), the latest version is 0.7.0.

I did not use version 0.7.0 because it has a compile dependency on clickhouse-http-client:0.7.0-SNAPSHOT (https://mvnrepository.com/artifact/com.clickhouse/clickhouse-jdbc/0.7.0).

Additionally, I verified the driver locally with the following test:

@Testcontainers(disabledWithoutDocker = true)
class ClickhouseIntegrationTests {

	@Container
	static final ClickHouseContainer clickhouse = new ClickHouseContainer("clickhouse/clickhouse-server:24-alpine")
		.withUsername("test")
		.withPassword("password");

	@Test
	void shouldConnectToClickhouse ()  {
		String jdbcUrl = clickhouse.getJdbcUrl();
		SimpleDriverDataSource dataSource = DataSourceBuilder.create()
			.type(SimpleDriverDataSource.class)
			.url(jdbcUrl)
			.username("test")
			.password("password")
			.build();
		new JdbcTemplate(dataSource).execute(DatabaseDriver.CLICKHOUSE.getValidationQuery());
	}

}

By the way, when I updated the version to 0.7.0, Gradle was against this:

Execution failed for task ':spring-boot-project:spring-boot:compileKotlin'.
> Could not resolve all files for configuration ':spring-boot-project:spring-boot:compileClasspath'.
   > Could not find com.clickhouse:clickhouse-http-client:0.7.0-SNAPSHOT.

         project :spring-boot-project:spring-boot > com.clickhouse:clickhouse-jdbc:0.7.0

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

0.7.0 could be used but this requires adding an additional module:

modules = [
    "clickhouse-jdbc",
    **"clickhouse-http-client"**
]

Thanks @nosan! Given that we don't really have any direct integration with ClickHouse, I've removed it as a managed dependency. I think this is a good middle ground that means we can support the URLs without needing to worry about which version to depend on.

Thank you, @philwebb
