Bug#1120462: apt: Mention Debug::APT::Solver in apt.conf.5

[Tianyu Chen <sweetyfish@deepin.org>]

Package: apt
Version: 3.1.11
Severity: wishlist
X-Debbugs-Cc: sweetyfish@deepin.org

Hi,

apt.conf.5 does mention some debug options, but Debug::APT::Solver is
missing from them. Please consider also mentioning that in apt.conf.5.

Thanks!

Best regards,
