[GoFr-SOC]: Couchbase support

[olxandr]

Problem:
GoFr does not yet support Couchbase, a widely-used NoSQL document database ideal for flexible data models, high-performance applications, and real-time analytics. Making Couchbase a native datasource in GoFr will allow seamless storage and querying of document-oriented data.

Solution:
Goal:
Add a new datasource in pkg/gofr/datasource/couchbase.
Add method on App to plug and use the datasource.

Include:
Logging: Log each operation and failure with context.
Tracing: Wrap calls in OpenTelemetry spans.
Metrics: Emit Prometheus metrics for operation counts and errors.

@olxandr, Sure assigning this issue to you. However please do check if Couchbase is already compatible with any of the driver implementations that GoFr already has. We can supposedly use the same for Couchbase methods also instead of making it a completely different new package.

I'll look into it
