Add shared Docker network and Miniflux plugin for Hermes

- Create external 'monotrope' Docker network so services can
  communicate by container name
- Add Miniflux to the shared network (db stays on internal network)
- Add Hermes Miniflux plugin with list_feeds and get_unread_entries tools
- Mount plugin directory and pass Miniflux API key to Hermes container
