[FR] Honor prometheus.yaml params

[adean-consensys]

Feature Request for Prometheus queries to honor scrape_config params to reduce the complexity of Prometheus service monitors.

Example:

 job_name: listaccounts
  metrics_path: /list_accounts
  params:
    module: ["account"]
    action: ["listaccounts"]
  static_configs:
    - targets:
      - https://example.org/api

A request to localhost:7979/list_accounts?target=https://example.org/api would be the same as a query to localhost:7979/list_accounts?target=https://example.org/api?action=listaccounts&module=account
