progress: demonstrate non-linear progress has a bad ETA experience

Previously, the ETA and speed assumes the progress is linear. Often, due to
network or other issues, it could be fast for the most time, and suddenly
slow down:

    [====================================================>         ]
     \___________________________________________/\______/
        very fast                                  suddenly much slower

This patch adds a test demonstrating the ETA could be way off in those
cases.
