Fixes#9960
This adds the output of a "Backing Filesystem:" entry to `docker info`
to overlay, aufs, and devicemapper graphdrivers. The default list
includes a fairly complete list of common filesystem names from
linux/include/uapi/linux/magic.h, but if the backing filesystem is not
recognized, the code will simply show "<unknown>"

The documentation on `docker export` doesn't mention that
data in volumes is not included in the export.
This adds a note that volumes are not part of the export
and refers to the "Backup, restore, or migrate data volumes"
to give the user some pointers.

Add a --readonly flag to allow the container's root filesystem to be
mounted as readonly. This can be used in combination with volumes to
force a container's process to only write to locations that will be
persisted. This is useful in many cases where the admin controls where
they would like developers to write files and error on any other
locations.

We want to be able to use container without the PID namespace. We basically
want containers that can manage the host os, which I call Super Privileged
Containers. We eventually would like to get to the point where the only
namespace we use is the MNT namespace to bring the Apps userspace with it.
By eliminating the PID namespace we can get better communication between the
host and the clients and potentially tools like strace and gdb become easier
to use. We also see tools like libvirtd running within a container telling
systemd to place a VM in a particular cgroup, we need to have communications of the PID.
I don't see us needing to share PID namespaces between containers, since this
is really what docker exec does.
So currently I see us just needing docker run --pid=host

This fixes the container start issue for containers which were started
on a daemon prior to the resolv.conf updater PR. The update code will
now safely ignore these containers (given they don't have a sha256 hash
to compare against) and will not attempt to update the resolv.conf
through their lifetime.

Only modifies non-running containers resolv.conf bind mount, and only if
the container has an unmodified resolv.conf compared to its contents at
container start time (so we don't overwrite manual/automated changes
within the container runtime). For containers which are running when
the host resolv.conf changes, the update will only be applied to the
container version of resolv.conf when the container is "bounced" down
and back up (e.g. stop/start or restart)

It seems odd to have such an important API hidden under 'misc'.
While in there I noticed that during the "-f Dockerfile" PR I changed
the query param from f to dockerfile and missed this one spot in the docs.

w/o this one-liner the v1.17 docs didn't appear in the Reference dropdown
and I would get a 404 when I tried to access
.../reference/api/docker_remote_api_v1.17/
Not sure if there are other spots that need to be fixed but this seemed to
fix it for me.
