New grpc uses failfast by default, but that code was written with other
default in mind, so just preserve it for now.

This adds an `--oom-score-adjust` flag to the daemon so that the value
provided can be set for the docker daemon's process. The default value
for the flag is -500. This will allow the docker daemon to have a
less chance of being killed before containers do. The default value for
processes is 0 with a min/max of -1000/1000.
-500 is a good middle ground because it is less than the default for
most processes and still not -1000 which basically means never kill this
process in an OOM condition on the host machine. The only processes on
my machine that have a score less than -500 are dbus at -900 and sshd
and xfce( my window manager ) at -1000. I don't think docker should be
set lower, by default, than dbus or sshd so that is why I chose -500.

This flags enables full support of daemonless containers in docker. It
ensures that docker does not stop containers on shutdown or restore and
properly reconnects to the container when restarted.
This is not the default because of backwards compat but should be the
desired outcome for people running containers in prod.

Its useful to have containerd logs as part of docker.
Containerd metrics are too chatty, so set interval to 0.
