Add generic "event of interest" enumerated histogram.
This change aims to simplify the addition of events we may
want to track in the field, more specifically hard-to-reproduce
bugs. Before this change, this requires creating a new histogram
and registering it via histograms.xml, which is not in the Chrome OS
repositories. With this change, a new event just requires claiming
an event name (such as ModemManagerCommandSendFailure) in
metrics_library.cc, and running "metrics_client -v <event name>"
or calling SendCrosEventToUMA(event_name).
I can make up a bug for this. Or not.
