rbd: rename setImageOptions() to constructImageOptions()

A function called `setImageOptions()` is expected to set the passed
options on the volume. However, the passed options parameter is only
filled with the options that should get set on the RBD-image at the time
of creation.

The naming of the function, and it's parameter is confusing. Rename the
function to `constructImageOptions()` and return the ImageOptions to
make it easier to understand.
