Reduce granularity of histogram buckets for Go 1.17 collector (#974) 
The Go runtime/metrics package currently exports extremely granular
histograms. Exponentially bucket any histogram with unit "seconds"
or "bytes" instead to dramatically reduce the number of buckets, and
thus the number of metrics.

This change also adds a test to check for expected cardinality to
prevent cardinality surprises in the future.
