Added logs command and integrated it into the CLI structure.

[PranavVerma-droid]

This pull request adds a new logs feature to the CLI tool, allowing users to get logs for specific services, components, or all pods in a namespace. The updates involve adding logic to interact with Kubernetes using kubectl commands and incorporating the new feature into the CLI framework.

New logs feature implementation:

• cli/src/logs.rs: A detailed implementation for the logs_command function was added, which retrieves logs through kubectl. It features helper functions for validating namespaces, retrieving pods based on service or component labels, and fetching logs for individual pods. A new Component enum was created to represent control-plane and data-plane components.

Integration into CLI framework:

• cli/src/main.rs:
  • The new logs module and command were registered in the CLI structure.
  • A LogsArgs struct was added to define arguments for the logs command, including service, component, and namespace.
  • The logs_command function was integrated into the CLI argument parser, allowing the execution of the logs command.
  • Imports were updated to include the logs module and its related command.

These updates improve the functionality of the CLI tool by giving users the ability to retrieve detailed logs directly from their Kubernetes cluster.

Consider optimizing the intersection of pods by converting one of the pod lists (e.g., component_pods) into a HashSet to reduce the time complexity from O(n²) to O(n).

Suggested change

	// intersection
	service_pods.into_iter()
	.filter(|pod| component_pods.contains(pod))
	let component_pods_set: HashSet<_> = component_pods.into_iter().collect();
	// intersection
	service_pods.into_iter()
	.filter(|pod| component_pods_set.contains(pod))
