Bug 1768255: replace Fraction with Done and Total

Make Done and Total available to syncStatus and calculate percent
complete locally. Use math.Trunc to avoid rounding which occurs
when only %.0f is used. This can also cause us to display 100%
complete when Done != Total.

Also dropped pkg/cvo/cvo_scenarios_test.go's use of diff.ObjectReflectDiff.
Method was causing a panic and is also deprecated in favor of cmp.Diff.
cmp.Diff does not print out difference so simply logged expected and actual
values instead.
