feat: add Terminal API and Custom Resource Definition for interactive…

[iasthc]

This pull request introduces a new "Terminal" custom resource definition (CRD) to support user-interactive kubectl session pods managed by the console operator. It adds the API schema, Go type definitions, and registers the resource with the Kubernetes API machinery. The changes also update documentation and kustomization to include the new CRD.

Introduction of Terminal CRD and supporting code:

• Adds a new CRD manifest for Terminal resources in config/crd/bases/console.otterscale.io_terminals.yaml, defining the schema, validation rules, status fields, and additional printer columns for kubectl output.
• Updates config/crd/kustomization.yaml to include the new Terminal CRD in the kustomize build.

Go API types and registration:

• Implements Go type definitions for the Terminal resource, including Terminal, TerminalList, TerminalSpec, TerminalStatus, and supporting types in console/v1alpha1/terminal_types.go. These types capture the CRD schema and validation logic.
• Registers the Terminal resource types with the Kubernetes API machinery in console/v1alpha1/groupversion_info.go, enabling the controller to work with these resources.

Documentation:

• Updates the README.md to document the new Terminal resource, its group, scope, and purpose in the CRD table.… kubectl sessions

Pull request overview

This PR introduces a new Terminal Custom Resource Definition (CRD) under console.otterscale.io/v1alpha1, along with the corresponding Go API types and scheme registration so other components (e.g., the console operator) can create/read/update these resources and generate CRD manifests.

Changes:

• Adds the Terminal CRD manifest (schema, validation rules, printer columns, and status subresource).
• Adds console/v1alpha1 Go API types (including spec/status) plus generated deepcopy code and scheme registration.
• Updates CRD kustomization and README to include/document the new resource.
