TUN-4116: Ingore credentials-file setting in configuration file during tunnel create and delete opeations.

Browse Source 
This change has two parts:
1. Update to newer version of the urfave/cli fork that correctly sets flag value along the context hierarchy while respecting config file overide behavior of the most specific instance of the flag.
2. Redefine --credentials-file flag so that create and delete subcommand don't use value from the config file.
