Plan status output should be sorted

[yankcrime]

What happened:
When running the plan status command via the CLI, the output isn't sorted in any way and can change each time it's run.

What you expected to happen:
Consistent output for this command.

The ordering isn't necessarily important (although it would make sense if the deploy plan was always first), but I think it needs to be consistent.

How to reproduce it (as minimally and precisely as possible):

Run kubectl kudo plan status --instance my-instance a couple of times, the order of the plans as they're displayed changes.
