Remove some of the keyword arguments in the confirm modules

[riverrun]

In the confirm modules, keyword arguments can be used to overwrite the default config values.

This was first introduced to help support umbrella apps (due to the way the config files are handled), but I think this is probably no longer needed. The config for the user_context and endpoint can be set in the Endpoint module, and it is only in rare cases that a developer would want to overwrite those values. Even if a developer does want to overwrite them, he / she can still do so by use-ing the base module.

What do people think about removing these keyword argument options (and relying on the config values)?

• Authenticate, AuthenticateToken and Remember:
  • user_context
• Confirm and Confirm.PassReset:
  • user_context
  • endpoint (or key_source)
