feat: support otel for sdk

[chenhuansome]

What problem does this PR solve?

Provides distributed tracing capability for the OpenGemini Java client, enabling users to achieve call chain visualization, performance analysis, and troubleshooting through the OpenTelemetry ecosystem (such as Jaeger), thereby enhancing system observability.

What is changed and how it works?

1. Added the  Interceptor  interface and  OtelInterceptor  implementation to insert OpenTelemetry tracing logic before and after query (Query) and write (Write) operations, including Span creation, attribute setting, and status marking.

2. Extended the  Query  and  Write  classes by adding a  Map<String, Object>  attribute map to store context information such as tracing Spans.

3. Modified the  OpenGeminiClient  class to introduce an interceptor flow when executing query and write operations, ensuring the tracing logic is triggered.

4. Added the  OpenTelemetryConfig  configuration class and related dependency management to support the configuration and use of Tracer.

How has this been tested?

Configure an OpenTelemetry exporter (Jaeger), execute query and write operations, and verify whether tracing data is generated and reported normally, ensuring that the creation, attributes, and status of Spans meet expectations.
