Add more info to containers

[joaquimrocha]

As pointed out in #1929 , we should add the following info to the pods:

Pod List:

• Add quick status for each container (design TBD)

Pod Details:

• Add exit code for containers
• Add started/finished times
• Add restart reason

@joaquimrocha Hi
for point "Pod Details (for those with completed containers)" I would say not only with completed but also for running, the container could have been killed and restarted, but is currently running so it is also useful to get restart reason

Reopening for tackling the last item.

Most parts are done, but there's one item left open. Moving this to the next release milestone.
