[Refactor] rewrite the whole operator into rust

[ZhiHanZ]

Currently operator follows the traditional approach using kube-builder and client-gen for CRD and client API generation.
Here have several things may become blocker for future use cases.

1. bendctl(command line tool for databend) needs to maintain another CRD written in Rust which may introduce compatibility issues during version upgrade
2. openapi semantics generated from rust-based CRDs are different from openapi semantics generated from cuelang(openapi gen standardisation pre-donation kube-rs/kube#606)

pros of operator written in Rust:

1. no compatibility issues during code-generation
2. smaller memory and resource usage(https://www.reddit.com/r/rust/comments/pzcu62/linkerd_211_now_includes_a_kubernetes_controller/)
