Ignore the image entrypoint when creating job/sandbox containers

Given that user can now push any docker images (!204), we will
have troubles if the user sets an arbitrary entrypoint (eg: using
the ENTRYPOINT instruction in the Dockerfile).

It is wiser to just ignore the entrypoint for the moment.

Note: in the future, we should remove Webapp.entrypoint and use the
ENTRYPOINT defined in the image instead.
