feat: Support Karpenter NodeClaim API in workspace

[helayoty]

Reason for Change:

• Workspace controller can support nodeClaims API.

Workspace controller won't migrate the current machine nodes. The behavior for CRUD operation:

Create

• Both nodeClaims or Machine APIs will be used to create a node based on featureGate,

Ownership

• Both machines and nodeClaims objects which created by the same workspace will be associated to it until got deleted.

Delete

• Deleting the workspace will delete both (if any) old machines objects and nodeClaims.

• Add unit tests for supporting node claims, and managing migrated clusters (both machines and nodeClaims).

• Replace the deprecated func FromInt with FromInt32.

• Update error message lint warning, start with lowercase characters.

Requirements

• added unit tests and e2e tests (if applicable).

Issue Fixed:
#339

@bangqipropel any k8s version before 1.29 will use machine API. Otherwise, the nodeClaim API will be used.

I see, before I saw 1.27 also, that was why I asked
