Make image inspect more in line with other tables

[rumpl]

- What I did

Changed the output of docker app image inspect to be more in line with other tables the cli has:

version: 0.1.0
name: voting-app
description: Dogs or cats?
maintainers:
- name: user
  email: user@email.com


SERVICE REPLICAS PORTS IMAGE
db      1        5432  postgres:9.4
redis   1        6379  redis:alpine
result  1        5001  dockersamples/examplevotingapp_result:before
vote    2        5000  dockersamples/examplevotingapp_vote:before
worker  1              dockersamples/examplevotingapp_worker

PARAMETER     VALUE
