Photobomb performs workflow tests against the ESP REST API.

It uses the client and structs provided by the ESP SDK package.

• auto-refresh token once it expires
• SPA front-end using a Javascript framework
• long-running server-to-browser connections via Websockets or HTTP/2
• auto-reload config.json
• graceful shutdown by trapping signals from OS
• track (and display in UI) per-bomb and per-missile stats
• send logs to Splunk/Logstash
• configurable latency threshold(s) to pass a health check
  • any workflow can have a health check that passes only once the workflow execution limit falls under the threshold ("warm-up")
  • a secondary health check can fail when the execution limit is exceeded, optionally auto-scaling
