Writing the Common Utility for Async Function Handling , ApiResponse, ApiError

[MOHINI1403]

• Writing the common utility for handling Asynchronous function so that we can avoid the job of writing try...catch block again and again and just wrapping our method in this utility.
• Writing the common utility function for handling ApiError and ApiResponse for structuring the response in the way that improves the code refactoring, code quality and a standard format is followed by all the response and error messages.
• Making desired changes into the code wherever necessary.
• Writing comments wherever necessary to help in better understanding the code.
