This change modifies the *-by-size metrics' units to be based off the
bucket's unit (bytes) as opposed to the unit of the counts (objects).
This convention is more in-line with distributions in other metrics
systems.

This change adds an additional line explaining the ordering of the
supported metrics list. It's also necessary to ensure "Supported
metrics" is displayed by godoc as a proper header.
This modification does mean the description test, that ensures
descriptions line up with documentation, needs to change slightly
so it it doesn't read this new line as documentation. Make this
new line the line the test uses to decide when to begin.
