Its for the review-comments onhttps://github.com/apache/pull/5299/files.

changes:

1. Main difference: All enums have got their own class. The implementation are extending an abstract-class "RetryReasonCategory " which exposes following pacakge-protected methods. These methods are not public. There is a public method "captureAndGetAbbreviation" in the abstract class which call these methods.:
   1. canCapture: returns if the server-response error can be categorized by the implementation.
   2. getAbbreviation: returns the abbreviation corresponding to the server response error.
2. RetryReason has a list of implementations of RetryReasonCategory which is sorted by their significance.
3. Test-class "TestRetryReason" has been added to test each subclass of RetryReasonCategory impelmentation.
