Jakub Roztocil a49774d3ab Extend auth plugin API
This extends the `AuthPlugin` API by the following attributes:

* `auth_require`: set to `False` to make `--auth, -a` optional
* `auth_parse`: set to `False` to disable `username:password` parsing
  (access the raw value passed to `-a` via `self.raw_auth`).
* `prompt_password`: set to`False` to disable password prompt when
   no password provided (only relevant when `auth_parse == True`)

 These changes should be 100% backwards-compatible.

 What needs more testing is auth support in sessions.
