Review Comment:
Can we just move buildMetricsContextAndMetrics() to the constructor of
HighLevelConsumer and avoid overriding startUp?

> We encounter a NullPointerException when initializing the
> DagActionStoreMonitor after moving the loading of DagActions on startup from
> the DagManager to the DagActionStoreMonitor. Metrics for the
> DagActionStoreMonitor were initialized by its parent class the
> HighLevelConsumer only before starting to consume Kafka messages, however
> with the refactor these metrics are needed beforehand. In this PR I separate
> the creation of these metrics into a separate function and call it before
> loading dagActions.
