[Merge] lp:~thomas-voss/net-cpp/bug-fixing-and-features-landing into lp:net-cpp

[Gary.Wang]

Review: Approve

Thanks tvoss for this MP, it looks good to me.
In this MP, I didn't see pause/resume issue anymore.
I think i should put speed.{limit, duration} into Request::Configuration struct in my MP just as what you do in this MP since we already have this struct there.
I really like the implementation of progress bar, it's quite neat and simple.
Thanks again.

P.S  I forget we have sth available in CI labs. :)
