Rename the input argument to image in the ndimage functions

[akhalighi]

This PR implements the following:

1. The wrappers for functions ported from scipy.ndimage are modified to rename the input argument to image.

2. The _get_docstring utility function for filters is modified to:

   • replace the input keyword with image when porting docstrings.
   • drop Examples from the original docstring in scipy.ndimage since they most probably will be invalid for the dask-image wrappers.

This is great! 😄

We also need to change the labels=None keyword argument to be label_image=None, and then do the same kind thing you've just done for the _get_docstring utility function. Is that something you'd like to do as well, or do you prefer someone else do that before merging the PR?

@GenevieveBuckley sure, it sounds fun. I will give it a shot!

FYI: I'm to integrating the changes we made to our CI builds (so we can see the tests pass on your branch). I might also merge this in soon, and leave the labels --> label_image change open for a separate PR.

🎉 Yay, merged! 🎉
Thanks so much @akhalighi, your contribution is very useful to have - makes things a lot nicer :)

Thanks @akhalighi for working on this and @GenevieveBuckley for the review!

Also just realized I hadn't opened the SciPy issue about renaming input in these functions. Have just now done so. ( scipy/scipy#10592 )
