As of the Linux 5.9 kernel a fallthrough macro has been added which
should be used to anotate all intentional fallthrough paths. Once
all of the kernel code paths have been updated to use fallthrough
the -Wimplicit-fallthrough option will because the default. To
avoid warnings in the OpenZFS code base when this happens apply
the fallthrough macro.

Previously, zpool-iostat did not display any data regarding rebuild I/Os
in either the latency/size histograms (-w/-l/-r) or the queue data (-q).
This fix essentially utilizes the existing infrastructure for tracking
rebuild queue data and displays this data in the proper places within
zpool-iostat's output.

A zpool_influxdb command is introduced to ease the collection
of zpool statistics into the InfluxDB time-series database.
Examples are given on how to integrate with the telegraf
statistics aggregator, a companion to influxdb.
Finally, a grafana dashboard template is included to show
how pool latency distributions can be visualized in a
ZFS + telegraf + influxdb + grafana environment.
