Show uptime docker compose

[zelahi]

Resolves #6867

Problem Statement:
In this PR, we are reporting the output when the user executes docker-compose ps after launching containers via docker-compose up

Expected Output

Implementation Details
I currently used the dateutils library and retrieved the uptimes from the container properties. After doing so, parsed them and displayed it in a human readable format. I added one unit test, but had trouble writing an unit test with the code path using datetime.now(). I didn't see any mocks, but I am open to suggestions and/or okay with reimplementing this without using pyzar and/or dateutils

Wondering why you didn't use the Status field that's returned by the API (which is the field that's used by the docker CLI;

curl --unix-socket /var/run/docker.sock "http://localhost/containers/json" | jq .

I agree with this. Also, if it's not running, there is no Uptime.
Changing the State column to Status would do the job.

The only thing here is the people that could be parsing this output, but since it's not a guaranteed format, we should be fine.

Ahh I believe I just missed it. I didn't use the curl command and actually used the values I saw when I did a docker inspect <container_name>. I'll go ahead and fix it so we use Status instead. Thanks for the feedback!! =)

IMHO, replacing State with Status would be a better approach.
