Build a step profile smartly.
The canonical way to build a step profile is to provide it with a
step function, `*args` and `**kwargs`. But in this function we're
being a little smarter so the user will have less work.
You do not need to enter a step function; we will use the default
one, unless you specify a different one as `step_function`.
You may also pass in a step profile as `step_profile`, and it will
be noticed and used.
