Ticket 51008 - dbhome in containers
Bug Description: When starting 389 in containers, the shm may be too
small. Mark fixed this in #51007, but it removed the ability to have
the dbhome in a tmpfs/shm.
Fix Description: Move the request for dbhome/container logic into
the dscontainer entry point instead to keep the setup.py simpler,
and make the dbhome in /data/run/dbhome allowing people to use
an shm for dbhome with '--tmpfs /data/run/dbhome:rw' to a docker
run or create command.
