ORNL-14: debug: print recovery completion message

Print a proper "end of recovery" message to match the one printed
by 1.x so that it is clear when recovery has finished, how long it
took, and how many clients recovered.

This should have been part of the original patch committed for
eda8eab5abeef1117ae1082533b5888a91875e12.
