kapp gets confused when ordering of fields isn't deterministic

[voor]

What steps did you take:
Some custom resources, like for example AWSCluster in Cluster API AWS, do not guarantee consistent ordering of entries. This causes kapp to fail in validating whether something truly needs to be updated.

What happened:
Given an array:

1
2
3

if that array is somehow changed in order:

3
2
1

then kapp will believe that the array has changed, and make updates accordingly.

What did you expect:
Since array ordering is actually a modification, this issue might be very difficult to truly tackle, so I reckon kapp thinking the object has changed is the intended result.

Anything else you would like to add:
Maybe the real problem here is that there needs to be a rebase rule to say an array's ordering isn't important, which would be nondefault behavior?

Environment:

• kapp version (use kapp --version):
• OS (e.g. from /etc/os-release):
• Kubernetes version (use kubectl version)
