Michael Crosby 89986cbff4 Add --oom-score-adjust to daemon
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.
