Bug#925439: Add option to limit parallel download

[積丹尼 Dan Jacobson <jidanni@jidanni.org>]

Package: apt
Version: 1.8.0
Severity: minor

Here we observe parallel download:

# aptitude full-upgrade
...
35% [5 firefox 33.9 MB/44.5 MB 76%] [1 google-earth-pro-stable 2,215 kB/56.5 MB 4%]

What if we don't want parallel download?
I.e., just download one server at a time?

Well the closest setting one finds in
/usr/share/doc/apt/examples/configure-index.gz
is acquire::queuehost::limit but that doesn't govern it.
