Add services column to docker app ls command

[silvin-lubecki]

- What I did
The current docker app ls command relies only on parsing claims in the local claim store and its last action, so it is totally uncorrelated with the current app status.

• List all the required services and the running services

- How I did it

• Tries to call status json action on all installed app and parses the json output with services description and their status. The ls command aggregates all those services, and counts how many are running and how many are desired (from the bundle).

- How to verify it

Can't understand the change to installerContext. Would at least request a comment if there's a legitimate reason.

[ndeloof]

I didn't took time to create a formatter for app ls command, but we should for homogeneity. Will look into this in a future PR.
