Fix aws flaking Unit Tests

[Jeffwan]

Looks like this Unit Test blocks several tasks. I notice someone comment this test and I think we can use MatchedBy to customize comparison logic.

This will resolve #1346 and other dependent issues for 1.2

I run hack/verify-gofmt.sh and found several files are not formatted and then run gofmt -s -w ${filename} Not sure if that's needed. if not, I will remove second commit

@aleksandra-malinowska Looks like create those two issues. Could you help take a look at this change?

[losipiuk]

@Jeffwan Is it only related to 1.2 branch all should be changed on other branches too?

@losipiuk Looks like it's disabled since this April and all release after 1.2 can be fixed by cherry-picking this commit. Do you want me to cherry-pick and submit PR against all latest branches? Since there're many branches, how do we deal with this issue normally?

Branches:

• cluster-autoscaler-release-1.3
• cluster-autoscaler-release-1.12
• cluster-autoscaler-release-1.13
• master

and also

• vpa-release-0.2
• vpa-release-0.3

[losipiuk]

@Jeffwan It would be great if you could cherry pick to at least master. Other CA release branches optionally. Skip vpa please.

This need to be separate PRs. We do not have any cp automation.

Thanks.

@losipiuk Thanks for guidance. Will do.
