Add docker daemon command instead of -d 

QE Reports that you can put lots of bogus options on the cli before the command
which are ignored if you specify a command.  We should report a usage error
if a user does this.

I believe a better long term solution would be to remove the -d options and add a daemon command.  This would make the handling of options the same for all use
cases.
