8b85c68c9e pkg: propagate metric providers context 
In custom-metrics-apiserver v1.22.0, contexts were added to the metric
providers. We can benefit from that by propagating the context given to
the provider down to the requests.

0b3ac78d19 pkg/resourceprovider: guard from negative metrics 
When serving the resource metrics API, prometheus-adapter may return
negative values for pods/nodes memory and CPU usage. This happens
because Prometheus sees counter resets which results in Prometheus
interpolating data incorrectly to avoid the counter value going down.
To prevent that, we need to add some guards in prometheus-adapter to
replace the negative value by zero whenever it detects one.

76e61d47f6 pkg/resourceprovider: prevent metrics-server panic 
The code that we are reusing from metrics-server to call
GetContainerMetrics and GetNodeMetrics requires that both functions
returns arrays of lengths of the number of pods/nodes given as
arguments. In some cases, prometheus-adapter was returning nil which
caused panics in metrics-server code.

3ae38c7417 Allow metrics to be defined as namespaced: false 
When set to false, no namespace label will be set by the adapter based on the namespace
portion of the url in the request path.

This allows individual consumers to set namespace independent of the source kubernetes resource.

---

Example:

Given an adapter config like this:

```
    externalRules:
    - seriesQuery: 'nsq_topic_depth'
      resources:
        namespaced: false
```

An HPA could target a different namespace by setting it in the selector:

```
  - type: External
    external:
      metric:
        name: nsq_topic_depth
        selector:
          labelSelector:
            topic: my-topic
            namespace: nsq
```

This is useful for scaling on metrics from services that run in a differnt namespace than the source resource.
