parameters: move the confirm kwarg to Param

Whether a parameter is treated like password is determined by the
`password` class attribute defined in the Param class. Whether the CLI will
asks for confirmation of a password parameter depends on the value of the
`confirm` kwarg of the Password class.

Move the `confirm` kwarg from the Password class to the Param class, so
that it can be used by any Param subclass which has the `password` class
attribute set to True.

This fixes confirmation of the --key option of otptoken-add, which is a
Bytes subclass with `password` set to True.
