Would require changes to MapServer. Either creating a CONNECTION HILLSHADE (ala
CONTOUR), or something more generic that would enable to run an arbitrary executable
with options
Another way of doing it with GDAL 2.2 is to use VRT with pixel functions in Python:

There's actually one example to do (single direction) hillshading.
