Refactor reportAllRunningContainers to use worker goroutines

[thang14]

This pull request introduces several changes to the core/apps/app_report.go file to improve the efficiency and reliability of reporting on running containers. The key changes include the addition of concurrency for processing containers, the removal of the ticker, and the introduction of a new helper function to process individual containers.

Concurrency improvements:

• Added runtime and sync packages to support concurrent processing of containers.
• Implemented a worker pool using sync.WaitGroup and runtime.NumCPU() to process containers concurrently.

Refactoring and code simplification:

• Removed the time.Ticker and replaced it with a time.Sleep loop to simplify the reporting loop.
• Extracted container processing logic into a new helper function processReportContainer to improve code readability and maintainability.

Logging and error handling:

• Added logging to report the number of running containers found.
• Improved error handling by ensuring the function returns immediately upon encountering an error, rather than using continue.
