The endpoint and its parameters are now configurable on the filter itself, meaning each filter can have its own endpoint:

    "person": {
      "phEyeConfiguration": {
        "endpoint": "http://localhost:5000"
      },
      "personFilterStrategies": [{
        "strategy": "REDACT",
        "redactionFormat": "{{{REDACTED-%t}}}"
      }]
    },
