Some kpod commands were listed twice in main.go. Removed these
duplicates and alphabetized the remaining commands to prevent this
from happening in the future

Before exiting, have kpod shut down the storage library if it can. This
should keep us from leaving mountpoints for the root (for non-vfs cases)
and run directory (with newer containers/storage) busy when testing kpod.

Also set default level of logging to errors, we should not see
info messages in the kpod command line.
While adding this patch, I found missing options in kpod command line
and bash completions, so I added them in.
Also fixed some sorting issues in the way commands are displayer in help or in
bash completions.
Finally fixed the error message to be output on failure using logrus.Errorf, so
we don't get the stack any longer.
Also updated README.md with missing kpod commands.

kpod diff reports on differences between two layers, specified as
layer IDs, containers, or images. In the case of containers or
images, kpod diff produces a diff for the top layer

This command will allow users to manipulate and examine the container
images from outside of the container.

Need to mv to latest released and supported version of logrus
switch github.com/Sirupsen/logrus github.com/sirupsen/logrus
Also vendor in latest containers/storage and containers/image

Design: The output of the `info` subcommand ought to be directly
consumable in a format like JSON or yaml.
The structure being a map of sorts.
Each subsection of information being an individual cluster under the
top-level, like platform info, debug, storage, etc.
Even if there are errors under the top level key, the value will be a
map with the key of "error" and the value as the message of the
`err.Error()`. In this way, the command always returns usable output.
Ideally there will be a means for anything that can register info to do
so independently from it being in the single info.go, so this approach
is having a typed signature for the function that gives info, but i'm
sure it could be better.
Current iteration of this outputs the following as a limited user:
```yaml
host:
MemFree: 711307264
MemTotal: 2096222208
SwapFree: 2147479552
SwapTotal: 2147479552
arch: amd64
cpus: 1
os: linux
store:
error: 'mkdir /var/run/containers/storage: permission denied'
```
and as root (`sudo kpod info -D`):
```yaml
debug:
compiler: gc
go version: go1.7.6
goroutines: 3
host:
MemFree: 717795328
MemTotal: 2096222208
SwapFree: 2147479552
SwapTotal: 2147479552
arch: amd64
cpus: 1
os: linux
store:
ContainerStore:
number: 1
GraphDriverName: overlay2
GraphRoot: /var/lib/containers/storage
ImageStore:
number: 1
```
And with the `--json --debug` flag:
```json
{
"debug": {
"compiler": "gc",
"go version": "go1.7.6",
"goroutines": 3
},
"host": {
"MemFree": 709402624,

"GraphDriverName": "overlay2",

We now have actual kpod code, so no reason to have a not implemented feature.
Especially when we don't intend to create kpod launch.

'kpod images' lists all images on a system. 'kpod rmi' removes
one or more images from a system. The images will not be removed
if they are associated with a running container, unless the -f
option is used
