Obfuscation

[tbuchaillot]

As a Tyk viewer user, I'd like to specify with a struct field tag which fields need to be obfuscated by default. It should also allow a way to show raw content.

Example: http://username:password@mongourl/:mongoport/ - We can check in the code if the struct has X tag we can obfuscate it as http://****:****@mongo_url:port/

I think it's going to be easier if we obfuscate the whole instead of X patterns.
