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.

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
