Adjust timeout for Initial Network Check

The initial network check is used to detemrine whether the containers
need to be restarted or not. On initial setup they need a restart to get
the networking to work.

60 seconds makes the initial run a lot longer than it needs to be,
setting this much lower (10 seconds) will save time.
