Pre import image_upload to avoid loading it after asyncio has started

image_upload will always be setup because its a dep of person
and since person is a dep of onboarding which is a dep of
frontend its already a base requirement for homeassistant.

Pillow is now listed as a requirement for homeassistant
so we can be sure it installed by the time bootstrap is
loaded

image_upload loading is currently a bottleneck to
get the frontend loaded because it has to load in the
import executor when everything is busy early in startup
