I want to reduce some complexity around here, part of which is that
launch imported entrypoint imported backend, all to do some proxy
wrapping which isn't necessary for the dev case anyway. Less
layers of wrapping and importing is good. Plus I think this naming
is more clear.
Additionally, I realized that the entrypoint aka prod launcher was
never updated to init the ycdldb as that was only done by the argparse
launcher. Now it's hardcoded and I'll consider adding a config file.
