apt_install() / apt_uninstall() may fail if background process running
apt operation, such as unattended-upgrades.
To avoid this, we need to add two things:
1. For apt-get install / remove, we need to option "DPkg::Lock::Timeout=-1"
to wait for dpkg lock.
2. For apt-get update, there is no option to wait for cache lock.
Therefore, we need to implement retry-loop to wait for apt-get update
succeed.
