Break out event handling into its own function 
It's idiomatic in go to keep code indentation due to nested loops to a
minimum. Decoupling the events handling function into its own function
makes it easier to read the code and test the behavior in isolation of
the channel handling. It's now also easily possible to process events
in parallel without having to touch actual business code.

a144b1f9f7 feat: configurable quantiles for Summaries 
* Quantile values for a Summary are now configurable.

* The default quantiles (DefObjectives) in the prometheus Go client library is
deprecated. This commit removes the reliance on it.

cdf79ba2f9 Break out the telemetry during sample processing 
The "packets" metric had heavily overloaded meaning for different
"outcomes", and would often be incremented multiple times, sometimes
even with a single (per-line) increment in one outcome corresponding to
multiple increments in another.

This removes the broken metric, and replaces it with separate total and
error counters for each level of processing. This allows monitoring the
network traffic handled separately from the samples incurred by it.
