Description

This PR introduces the crdhandler package with a focus on handling CustomResourceDefinitions (CRDs) related to Github repositories. The main changes include:

• The addition of the GithubRepositoryHandler struct in the crdhandler/github package. This struct and its methods handle the initialization of the Github repository, extraction of frameworks, controls, rules, exceptions, and control configurations from the repository, and cleaning the repository.
• The addition of the CrdHandler struct in the crdhandler package. This struct and its methods handle the creation of frameworks, controls, rules, exceptions, and control configurations in the Kubernetes API.
• The addition of various types and structs in the crdhandler/github package, such as GithubRelease, GithubCommit, FrameworkJson, ControlJson, RuleJson, Framework, Control, Rule, Exception, and ControlConfiguration.
• The addition of utility functions for unzipping files in the crdhandler/github package.
• The update of main.go to include the creation of a CrdHandler instance and the handling of CRDs.
• The addition of the CrdHandler struct and the repositoryHandler interface in the crdhandler package.
• The addition of CustomResourceDefinition (CRD) for rules in the Kubernetes API.

PR Analysis

• 🎯 Main theme: Adding a new feature for handling CustomResourceDefinitions (CRDs) related to Github repositories.

• 📝 PR summary: This PR introduces the crdhandler package which handles CustomResourceDefinitions (CRDs) related to Github repositories. It includes the addition of several structs and methods for initializing the Github repository, extracting various components from the repository, creating these components in the Kubernetes API, and cleaning the repository. The PR also includes the addition of utility functions for unzipping files.

• 📌 Type of PR: Enhancement

• 🧪 Relevant tests added: No

• ⏱️ Estimated effort to review [1-5]: 4, because the PR introduces a significant amount of new code across multiple files, including complex logic for handling Github repositories and Kubernetes CRDs. The code is well-structured and clear, but it requires a good understanding of Kubernetes and Github APIs to review effectively.

• 🔒 Security concerns: No

  PR Feedback

• 💡 General suggestions: The PR is well-structured and the code is clear. However, it lacks tests to verify the functionality of the new code. It would be beneficial to add unit tests for the new methods and integration tests to ensure the correct interaction with the Github and Kubernetes APIs. Additionally, error handling could be improved in several places by not just logging the error but also returning it to the caller, allowing for more robust error handling.

• 🤖 Code feedback:

  relevant file	crdhandler/github/github.go
  suggestion	Consider returning errors from the InitRepository() method instead of just logging them. This would allow the caller to handle the error and decide whether it's fatal or not. [important]
  relevant line	func (grh *GithubRepositoryHandler) InitRepository() { // err ? have

  relevant file	crdhandler/github/github.go
  suggestion	Avoid ignoring errors when unmarshalling JSON. If the unmarshalling fails, the program might continue with invalid data. [important]
  relevant line	_ = json.Unmarshal([]byte(data), &frameworkJson)

  relevant file	crdhandler/github/github.go
  suggestion	Avoid ignoring errors when reading files. If the reading fails, the program might continue with invalid data. [important]
  relevant line	data, _ := os.ReadFile("artifacts/frameworks/" + file.Name())

  relevant file	crdhandler/github/github.go
  suggestion	Consider handling the error when creating a new file. If the file creation fails, the program might continue and cause a panic when trying to close the file. [important]
  relevant line	out, _ := os.Create(filename)
