When an Infix device is connected to a LAN where the gateway has yet to
connect to the Internet, the container script will fail pulling images
from any remote server.

Since execd until now only retries on netlink/inotify events, or manual
SIGUSR1, jobs would get stuck even though Internet connectivity had been
established. This patch fixes that with the addition of a retry timer
which runs while there are pending jobs in the queue.

Execute jobs on route changes
This is a generic job queue executor for work that needs network access.
For example creating a Docker container by downloading an image from the
network -- if the download fails execd retries the job whenever there
is a route change.
