chore: update error metrics report

[duyhungtnn]

Part of bucketeer-io/bucketeer#799
Related to #65

TODO

• Track the 3xx status code as "RedirectRequestException".
  • add response_code via labels
• Track the 413 status code as "PayloadTooLargeException"
• Track 408 status code, and we should handle it as a timeout error.
• Make iOS error handling consistent with Android SDK. Android handles more errors code than iOS SDK. That is ( 405, 502, 504)
• Implement adding more information via labels for Unknown errors, so we don't spend too much time debugging.
  • Add error_message and response_code to the ErrorMetricsEvent labels

I think .invalidHttpMethod should be added to this array, what do you think?

I don't think it will be called here, so I think XCTFail() is better, what do you think?
