Rework pruning to report reclaimed space
This change adds code to report the reclaimed space after a prune. Reclaimed space from volumes, images, and containers is recorded during the prune call in a PruneReport struct. These structs are collected into a slice during a system prune and processed afterwards to calculate the total reclaimed space. Closes #8658 Signed-off-by: Baron Lenardson <lenardson.baron@gmail.com>
