  1. tmpnet: Write config enabling metrics collection by prometheus 

    Temporary networks used for testing previously lacked an easy way to
enable metrics collection. This PR ensures that prometheus has what it
needs to scrape the metrics endpoints of a temporary network and
enables scraping of CI jobs using temporary networks.

- Write prometheus configuration to ~/.tmpnet/prometheus/file_sd_configs for
  each node on startup and remove it on shutdown. This enables scraping
  of all nodes in a network no matter when they are started.

  Ref: https://prometheus.io/docs/guides/file-sd/

- Add script to scrape temporary networks with agent-mode
  prometheus. Works locally and in CI
