Walkthrough
The pull request introduces a new API server functionality to the operator application. It modifies the command initialization to conditionally start an API server based on configuration flags. Additionally, it updates the options structure to include parameters for enabling the API server and specifying its port. A new package, apiserver, is created, implementing the HTTP server with endpoints for managing GreptimeDBCluster resources. Unit tests are also added to validate the API server's behavior using a mock Kubernetes client.

🐰 In the code, a new server hops,
With clusters to manage, it never stops.
Flags set to guide, ports to define,
API magic, oh how it shines!
Testing with care, all bugs we’ll chase,
In this rabbit’s realm, we find our place! 🐇✨
