Monitoring improvements

[sionovd]

• created an abstract class called MetricsCollector in the core
• moved the prometheus monitoring to a PrometheusCollector class in the contrib
• added a SplunkCollector class
• added a new metric which calculates the latency of the longest path in the pipeline (meaning how long it takes to grab a frame, create a prediction, and then output the result in the display)
• added minor fixes for the routine logger
