For commands that ask for JSON results, if the input to the Go JSON
marshaller is empty, it will return a byte array with a literal
"null" in it. If that is the case, we should output [] instead
as at least that is valid JSON and will not break consumers of the
data.

When a user enters a CLI with a StringFlags or StringSliceFlags and does not add
a value the CLI mistakently takes the next option and uses it as a value.
This usually ends up with an error like not enough options or others. Some times
it could also succeed, with weird results. This patch looks for any values that
begin with a "-" and return an error.

Fixed that problem so that it returns nothing

The getCommand func strips out unwanted characters around the
command of the container. The JSON output should use this func
like the regular ps output for both consistency and because
Python does a literal interpretation of the bracket [] characters
when consuming as JSON.

Consumers of the json output, like the atomic cli, need the ID of the
image for the container as well as the name. Specifically, it is used
to tract "used" and "vulnerable" images.

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.
