Open Fetcher

Fetcher is a concept in SkyWalking backend. It uses pulling mode rather than receiver, which read the data from the target systems. This mode is typically in some metrics SDKs, such as Prometheus.

Prometheus Fetcher

prometheus-fetcher:
  selector: ${SW_PROMETHEUS_FETCHER:default}
  default:
    active: ${SW_PROMETHEUS_FETCHER_ACTIVE:false}

TODO: More detail should be added when this fetcher provided.
