Markus Lehtonen fb6484fb8d deployment: add startupProbe for nfd-master 
This patch mitigates inadvertent termination of nfd-master pods by the
liveness probe on big clusters.

With a recent change nfd-master started to wait (block) for informer
caches to sync before starting the main loop. Consequently, this change
also made the gRPC health enpoint to not respond until the caches have
been synced. In big clusters the syncing the NodeFeature object cache
takes a long time as the objects are big and there's (at least) one per
each node in the cluster. Thus, in big clusters, the liveness probe
kicks in and kills the nfd-master pod before it's ready.

Node Feature Discovery

Node Feature Discovery (NFD) is a Kubernetes add-on for detecting hardware features and system configuration. Detected features are advertised as node labels. NFD provides flexible configuration and extension points for a wide range of vendor and application specific node labeling needs.

See NFD documentation for deployment instructions.
