> The NodeManager invokes an external binary (e.g. {{nvidia-smi}}) to discover
> attached GPUs. Right now, there is a hard-coded 10-second timeout on
> execution of this binary and a hard-coded max error count of 10, beyond which
> the NodeManager will stop attempting discovery. This change will provide new
> configuration properties to control both the timeout and the max errors,
> which is useful in environments where there may be a delay in binding the GPU
> to the host. Default values for the new configuration properties will be set
> so as to maintain the existing behavior.
