[theobarberbany]

Carry kubernetes#7449

• Set initial count to zero for various autoscaler error types (e.g., CloudProviderError, ApiCallError)
• Define failed scale-up reasons and initialize metrics (e.g., CloudProviderError, APIError)
• Initialize pod eviction result counters for success and failure cases
• Initialize skipped scale events for CPU and memory resource limits in both scale-up and scale-down directions

@JoelSpeed the bug specifies 4.12,13,14,15 - I would assume 4.16,17,18 as well though...

[theobarberbany]

/cherry-pick release-4.18

[JoelSpeed]

Let's start by going back to 4.16 and leave it there for now, unless there's a particular high need I don't think this warrants go further back
