Trigger an explicit scale up error when expander filters out all scale-up options

[mtrqq]

…ons.

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

Cluster autoscaler will silently fail the scale-up in case expander was not able to pick the best option, this change adds logs to capture this behavior as well as changes the status of the scale up from ScaleUpNoOptionsAvailable to ScaleUpError

Which issue(s) this PR fixes:

Fixes #

Special notes for your reviewer:

This should not affect expanders as BestOption semantics tells us that this interface is supposed to pick the best option out of available ones and not to filter them out completely even if any are available

Does this PR introduce a user-facing change?

Hi @mtrqq. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
