chore: clean-up and improve repository setup

[maximiliantech]

This pull request introduces significant updates to the Makefile, PROJECT, and README.md files to enhance the build process, streamline resource definitions, and improve documentation. Key changes include the restructuring of the Makefile for better organization and functionality, updates to resource paths in the PROJECT file, and expanded documentation in the README.md to provide more clarity and usability.

Build System Enhancements:

• Improved Makefile structure: Added new sections for build dependencies, testing, deployment, and local development utilities. This includes targets for downloading tools like kustomize, golangci-lint, and controller-gen, as well as new commands for creating and managing local kind clusters. [1] [2] [3]
• Enhanced linting and testing: Introduced lint and lint-fix targets for code quality checks and automated fixes, and restructured the test target for better integration with environment setup. [1] [2]

Resource Configuration Updates:

• Updated resource paths in PROJECT: Migrated several resources from v1beta1 to v1alpha1 for consistency and alignment with the latest API definitions. This affects resources like ClusterAccess, FederatedMetric, and FederatedManagedMetric.

Documentation Improvements:

• Expanded README.md: Added a detailed table of contents, resource type descriptions with links to CRD files, and sections on data sink integration and migration from legacy configurations. This improves accessibility and clarity for users and contributors. [1] [2]

These changes collectively improve the maintainability, usability, and developer experience of the project.

• The image repository path includes github.com in the URL, which looks unusual for a container registry. Please confirm the correct registry path (e.g., ghcr.io/sap/metrics-operator) and update accordingly.

• [nitpick] Using "pod" as the metadata name may conflict with built-in Pod resources and reduce clarity in examples. Consider using a more descriptive and unique example name, such as metric-pod-count.

Work in progress. Still cleaning up some stuff.

make dev-local-all fails. can you please check why?

@mirzakopic This error is resolved. I've also enhanced the README with more information on how to quickly get started. Looking forward to your review. Once this is merged, we can proceed in making the metrics-operator public from my side.

[maximiliantech]

Additionally, I would suggest to make a release after this PR is merged. 🚀

Lgtm, an example with an open search and metrics ingestion would be great. Maybe as a follow up?
