[PATCH] Add service recovery options for QGA on windows

[yshxxsjt715]

From: shenjiatong <yshxxsjt715@gmail.com>

Add default recovery options for QGA on windows. Previously, QGA
on windows will not try to restart service if it is down. This PS
add some default options for the first, second and other failures,
with an interval of 1min. Failure counter will reset after 1 day.
