DaemonSet e2e: Update image and rolling upgrade test timeout

Browse Source 
Use Nginx as the DaemonSet image instead of the ServeHostname image.
This was changed because the ServeHostname has a sleep after terminating
which makes it incompatible with the DaemonSet Rolling Upgrade e2e test.

In addition, make the DaemonSet Rolling Upgrade e2e test timeout a
function of the number of nodes that make up the cluster. This is
required because the more nodes there are, the longer the time it will
take to complete a rolling upgrade.
