Mahmood Ali 7a68d76160 client: wait for batched driver updated ...

Here we retain 0.8.7 behavior of waiting for driver fingerprints before
registering a node, with some timeout.  This is needed for system jobs,
as system job scheduling for node occur at node registration, and the
race might mean that a system job may not get placed on the node because
of missing drivers.

The timeout isn't strictly necessary, but raising it to 1 minute as it's
closer to indefinitely blocked than 1 second.  We need to keep the value
high enough to capture as much drivers/devices, but low enough that
doesn't risk blocking too long due to misbehaving plugin.
