Description

This PR introduces concurrency to the GenerateNetworkPolicy function in the networkpolicy.go file. The main changes include:

• The sync package has been imported to manage goroutines using sync.WaitGroup.
• The GenerateNetworkPolicy function has been modified to generate ingress and egress rules concurrently for each neighbor using goroutines.
• wg.add(1) is used to add a count to the WaitGroup before each goroutine is launched, and wg.Done() is used to signal the end of a goroutine's execution.
• wg.wait() is used to block until all goroutines have completed.

The `GenerateNetworkPolicy` function has been modified to use goroutines for generating ingress and egress rules for each neighbor, thus improving the performance by parallelizing the process. The `wg.wait()` function is used to ensure all goroutines have completed before proceeding.** +22/-12

• 🎯 Main theme: Introducing concurrency to the GenerateNetworkPolicy function
• 📝 PR summary: This PR modifies the GenerateNetworkPolicy function in the networkpolicy.go file to generate ingress and egress rules concurrently for each neighbor using goroutines. This is achieved by using the sync package to manage goroutines with sync.WaitGroup.
• 📌 Type of PR: Enhancement
• 🧪 Relevant tests added: No
• ⏱️ Estimated effort to review [1-5]: 3, because the PR introduces concurrency which can be tricky to get right and may require careful review to ensure there are no race conditions or other concurrency-related issues.
• 🔒 Security concerns: No security concerns found

  PR Feedback

💡 General suggestions: The PR is generally well done, introducing concurrency to improve the performance of the GenerateNetworkPolicy function. However, it would be beneficial to include tests to verify that the concurrent execution works as expected and does not introduce any race conditions or other issues.

🤖 Code feedback:

---

relevant file	pkg/apis/softwarecomposition/networkpolicy/networkpolicy.go
suggestion	Consider using a channel to collect the results from the goroutines instead of directly appending to the generatedNetworkPolicy.PoliciesRef and networkPolicy.Spec.Ingress/Egress slices. This could help avoid potential race conditions. [important]
relevant line	generatedNetworkPolicy.PoliciesRef = append(generatedNetworkPolicy.PoliciesRef, policyRefs...)

---

relevant file	pkg/apis/softwarecomposition/networkpolicy/networkpolicy.go
suggestion	It's a good practice to limit the number of goroutines that can be created concurrently. Consider using a semaphore or a worker pool to limit the number of concurrent goroutines. [medium]
relevant line	go func(neighborIngress softwarecomposition.NetworkNeighbor){
