// The generic failure collector collects issues that anomaly_detector catches
// that manifest as a single line logged to a log file.
// The flow looks like this:
// 1. One of the parsers in anomaly_detector flag an issue
// 2. anomaly_detector invokes crash_reporter with an appropriate flag
// 3. crash_reporter invokes a GenericFailureCollector instance
