Default cluster-resources and cluster-info collectors added in host only support bundle

[banjoh]

Bug Description

Collecting a host only collectors support bundle includes cluster-resources and cluster-info collectors.

Expected Behavior

Only host collectors should be in the spec

Steps To Reproduce

Use --dry-run to print the spec that would be used to collect the support bundle. Note the extra in-cluster specs

support-bundle https://raw.githubusercontent.com/replicatedhq/troubleshoot/main/examples/collect/host/cpu.yaml --dry-run
apiVersion: troubleshoot.sh/v1beta2
kind: SupportBundle
metadata:
  creationTimestamp: null
  name: merged-support-bundle-spec
spec:
  collectors:
  - clusterInfo: {}
  - clusterResources: {}
  hostCollectors:
  - cpu: {}
  - cpu: {}
  - cpu: {}
  - cpu: {}
status: {}

Additional Context

There is also an additional bug where collectors are getting duplicated. Note the number of - cpu: {} entries in the merged collector
