The hidden flag is used to override the path of the default mounts file
for testing purposes.
Also modified the secrets pkg to allow for this override to happen.

998fd2ece0 Functionality changes to the following flags
--group-add
	--blkio-weight-device
	--device-read-bps
	--device-write-bps
	--device-read-iops
	--device-write-iops

--group-add now supports group names as well as the gid associated with them.
All the --device flags work now with moderate changes to the code to support both
bps and iops.
Added tests for all the flags.

98b19aeb0c Refactor dependency checks from init() into public API
Instead of checking during init(), which could result in major
locking issues when used with pods, make our dependency checks in
the public API instead. This avoids doing them when we start pods
(where, because of the dependency graph, we can reasonably say
all dependencies are up before we start a container).

4553f2914c More gracefully handle unexpected storage deletion
We have other tools using containers/storage. They can delete our
containers in c/storage without us knowing. Try and handle this
better by warning instead of erroring when delete our storage and
it is already gone.

This does not handle cases where libpod thinks the container is
mounted, but it is not. This is harder to check for, because
c/storage Mount() and Unmount() take a layer, image, or container
and that complicates our "container no longer exists" question.
Further work is needed here.

b85b217f55 Stage3 Image Library
This represents the stage3 implementation for the image library.  At this point, we
are moving the image-centric functions to pkg/image including migration of args and
object-oriented references.  This is a not a one-for-one migration of funcs and some
funcs will need to continue to reside in runtime_img as they are overly specific to
libpod and probably not useful to others.

manually enumerating files to be bind mounted in.

a4701b5631 Add --dns-search, --dns-opt, --dns-server and --add-host.
Each of these options are destructive in nature, meaning if the user
adds one of them, all current ones are removed from the produced
resolv.conf.

* dns-server allows the user to specify dns servers.
* dns-opt allows the user to specify special resolv.conf options
* dns-search allows the user to specify search domains

The add-host option is not destructive and truly just adds the host
to /etc/hosts.
