Support SolarWinds Scaler

[gantrior]

Proposal

The solarwinds scaler allows the users to integrate KEDA with SolarWinds Observability and its data, allowing to autoscale on metrics that are collected by SWO K8s Collector and sent to SolarWinds Observability

I think that this is nice! Does SolarWinds observability offer a free tier that we can use for e2e tests?

There is 30-days free trial that can be used for E2E test purposes if that is sufficient.

I am concerned 30-days trieal is not enough. We need a permanent solution, we run these e2e tests during the lifetime of a scaler.

We will create dedicated permanent tenant on staging environment for this purpose, we will just need to make sure that API_TOKEN that scaler will use to query measurements will be set as secret in CI for E2E test. Is this suitable option?
