Add support for the "user" metadata. Related to #80.

[dduportal]

Hello there! Thanks for this cool tool!

The issue #80 mentions some metadata Image fields that are not available.

This PR implements the support for the field "user" which defines the default user of a container.
This is really useful when you want to check that an image is not launching container as root by default :)

I would to replace all my:

commandTests:
  - name: "whoami"
    command: "whoami"
    expectedOutput: ["app"]

with

metadataTest:
  user: app

LGTM, thanks for the contribution @dduportal!

Any estimated timeline on the next release with this enhancement? The readme states this field is valid in the Metadata test example, but I get field user not found in type v2.MetadataTest when I have this in my test definition yaml:

schemaVersion: "2.0.0"

metadataTest:
  user: "nameOfMyUser"

Good question @gregwhorley !

Ping @nkubala about the release?
