Title:
  util.mount_cb only supports passing through a single (positional)
  argument to the wrapped function

Status in cloud-init:
  Expired

Bug description:
  This makes it difficult to use with a function that needs to take more
  than a single positional parameter, or any keyword arguments; you have
  to partially apply the function before calling mount_cb.

  I propose adding `args` and `kwargs` parameters, which will be passed
  to the callback function using *args and **kwargs.  (For bonus points,
  refactor all current callsites to pass `args` so we can drop the
  `data` argument entirely.)
