Support Google Cloud Datastore as a datasource

[bryanwux]

Problem:

GoFr does not yet support Google Cloud Datastore, which is a widely used NoSQL document database service in the Google Cloud Platform ecosystem.

Goal:

• Implement datastore as a new NoSQL datastore in pkg/gofr/datasource/datastore.
• Add a method on the 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.

Hey @aryanmehrotra, I'd like to work on this. Can you assign me this?

@bryanwux, do you have a specific use case for Google Cloud Datastore, or are you suggesting it as an essential addition to GoFr's roadmap?

@coolwednesday yea we have a project that heavily relies on google cloud datastore currently, and we are thinking about integrate it with GoFr. And I think at the same time it's an essential addition to GoFr's roadmap as well. If possible, could you please assign this to me? I have an ongoing work on this already.

Sure, assigning it to you. Please make sure to make it an external module. Refer to exisiting datasources for the same.
