allows troubleshoot to collect and analyze CPU micro architecture. this
is an usage example:
```yaml
apiVersion: troubleshoot.sh/v1beta2
kind: HostPreflight
metadata:
name: ec-cluster-preflight
spec:
collectors:
- cpu: {}
analyzers:
- cpu:
checkName: CPU
outcomes:
- pass:
when: 'supports x86-64-v2'
message: CPU supports x86-64-v2
- fail:
message: CPU does not support x86-64-v2
```
* feat: Install goldpinger if one does not exist when running goldpinger collector
- Deploy golpinger daemonset if one is not detected in the cluster
- Clean up all deployed resources
- Add delay to allow users to wait for goldpinger to perform checks
