Cleanup: Centralize Plugin Names in Plugin Interfaces

[camilamacedo86]

What do you want to happen?

Description: Currently, in various parts of the code, we use hardcoded constants to represent plugin names or keys, such as grafanaPluginKey and deployImagePluginKey in pkg/cli/alpha/internal/generate.go. This approach leads to redundant declarations of plugin names across different locations. For example, in the alpha generate command:

kubebuilder/pkg/cli/alpha/internal/generate.go

Lines 43 to 47 in a9ee390

	const (
	defaultOutputDir = "output-dir"
	grafanaPluginKey = "grafana.kubebuilder.io/v1-alpha"
	deployImagePluginKey = "deploy-image.go.kubebuilder.io/v1-alpha"
	)

Proposal

To improve maintainability and readability, we should:

1. Refactor to use centralized plugin name retrieval: Replace direct constant usage with Plugin{}.Name() or equivalent methods wherever possible.
2. Review existing plugins for potential updates: Ensure all plugins have a standardized method (like Name()) in their interface for retrieving their identifiers or names.
3. Reduce redundancy: Centralize and reuse plugin keys within the plugin interfaces rather than hardcoding them in multiple files.

This will help ensure consistency and make it easier to update plugin keys in the future.

Examples

• In the Golang v4 plugin, we have a Name() method that returns the plugin name:
  Golang Plugin Name Method

By leveraging similar methods across plugins, we can avoid the need for hardcoded keys like grafanaPluginKey or deployImagePluginKey.

Hi @bavarianbidi,

This PR is unrelated to the changes made in kubebuilder/pull/4319. The focus here is on improving maintainability by centralizing the plugin’s name retrieval.

Instead of defining constants with the full plugin name across various files, we can initialize the plugin and access its name dynamically using Plugin{}.Name()(for example). This cleanup has no impact on end-users and is purely for maintainers to streamline the codebase. PS.: this change would be applied ONLY in go files, no shell or md ones

This simplifies our work, ensuring consistency and reducing duplication.

Thanks!
