Added command line options for image file and command

Started the initial work to have command line options for the cli.  Image and command are required now and we can add options for debugging and other things terrible.
Usage from docker:

```
Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

Run a command in a new container

  -a, --attach=[]            Attach to stdin, stdout or stderr.
  -c, --cpu-shares=0         CPU shares (relative weight)
  --cidfile=""               Write the container ID to the file
  --cpuset=""                CPUs in which to allow execution (0-3, 0,1)
  -d, --detach=false         Detached mode: Run container in the background, print new container id
  --dns=[]                   Set custom dns servers
  --dns-search=[]            Set custom dns search domains
  -e, --env=[]               Set environment variables
  --entrypoint=""            Overwrite the default entrypoint of the image
  --env-file=[]              Read in a line delimited file of ENV variables
  --expose=[]                Expose a port from the container without publishing it to your host
  -h, --hostname=""          Container host name
  -i, --interactive=false    Keep stdin open even if not attached
  --link=[]                  Add link to another container (name:alias)
  --lxc-conf=[]              (lxc exec-driver only) Add custom lxc options --lxc-conf="lxc.cgroup.cpuset.cpus = 0,1"
  -m, --memory=""            Memory limit (format: <number><optional unit>, where unit = b, k, m or g)
  --name=""                  Assign a name to the container
  --net="bridge"             Set the Network mode for the container
                               'bridge': creates a new network stack for the container on the docker bridge
                               'none': no networking for this container
                               'container:<name|id>': reuses another container network stack
                               'host': use the host network stack inside the container.  Note: the host mode gives the container full access to local system services such as D-bus and is therefore considered insecure.
  -P, --publish-all=false    Publish all exposed ports to the host interfaces
  -p, --publish=[]           Publish a container's port to the host
                               format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort
                               (use 'docker port' to see the actual mapping)
  --privileged=false         Give extended privileges to this container
  --rm=false                 Automatically remove the container when it exits (incompatible with -d)
  --sig-proxy=true           Proxify received signals to the process (even in non-tty mode). SIGCHLD is not proxied.
  -t, --tty=false            Allocate a pseudo-tty
  -u, --user=""              Username or UID
  -v, --volume=[]            Bind mount a volume (e.g., from the host: -v /host:/container, from docker: -v /container)
  --volumes-from=[]          Mount volumes from the specified container(s)
  -w, --workdir=""           Working directory inside the container
```
