Fix metrics params for k8s service monitor

[ezio-auditore]

Currently the params are generated in k8sservice monitor to federate in-cluster kube metrics as below which is wrong. This patch fixes the correct string params.

params:
      match[]:
      - '{__name__=''kube_node_status_condition''}'
      - '{__name__=''kube_persistentvolume_info''}'
      - '{__name__=''kube_storageclass_info''}'
      - '{__name__=''kube_persistentvolumeclaim_info''}'
      - '{__name__=''kube_deployment_spec_replicas''}'
      - '{__name__=''kube_pod_status_phase''}'
      - '{__name__=''kubelet_volume_stats_capacity_bytes''}'
      - '{__name__=''kubelet_volume_stats_used_bytes''}'
      - '{__name__=''node_disk_read_time_seconds_total''}'
      - '{__name__=''node_disk_write_time_seconds_total''}'
      - '{__name__=''node_disk_reads_completed_total''}'
      - '{__name__=''node_disk_writes_completed_total''}'

Also fixed tech debt to fetch kube-rbac-proxy image from environment variables
