Have the "kpod info" command also package up the driver-level status
information that the github.com/containers/storage.Store's Status()
method returns.

No reason to carry this temporary variable for documentation purposes.
If in the future we find that it is necessary to add a CLI option, we
can add the variable then.

Changed the JSON output to hold the actual type of the data.
For example the creation time of a container will be of form time.Time.
The human readable output modifies all the fields to type string, which
is not helpful when the JSON output wants to be used for further processing.

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.

We want all kpod subcommands to use the formats code to output
formats like json. Altering kpod diff --json to kpod diff --format json
like the kpod images command.

Add functions to go templates such as truncating a field. Also add
the table keyword, which, if placed at the beginning of a format string,
adds headers to the output

For kpod images, we need to output in JSON format so that consumers
(programatic) have structured input to work with.
kpod images --format json

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.

layer IDs, containers, or images. In the case of containers or

We already parse every image if there's a label filter so that we can
check against the filter, so when we do that, go ahead and read the
OCI-format configuration and inspection data as well, and use an image's
creation date as recorded in inspection data everywhere.

Make getStore() take a config struct from which it pulls the store
options, then update the kpod commands so that they call getConfig()
and pass the config into getStore()
Signed-off-by: Ryan Cole <rcyoalne@gmail.com>
Avoid parsing metadata that the image library keeps in order to find an
image's top layer and creation date; instead, use the values which the
storage library now makes available, which will be correct once we merge
PR #654 or something like it.
Instead of assuming the last blob which was added for the image was the
manifest, read it directly and compute its digest ourselves.

Bump containers/image (pulling in its new dependency on ostree-go),
containers/storage, and updated image-spec.
This pulls in the OCI v1.0 specifications and code that allows us to
support 1.0 images.

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": {
