Is your feature request related to a problem? Please describe.

We are using the OSS version of Tyk gateway. When troubleshooting 403 forbidden requests, I have difficulty correlating between the denied request and which API key is used. Adding additional information would make it a lot easier to debug

Describe the solution you'd like

Adding key hashed information along side with obfuscated key

Describe alternatives you've considered
