fast_schedule == 0 (i.e. the node's value is used directly rather
than the partition's configuration value).

Local code added that is built and used only as needed.

when a node becomes DOWN for not responding. This is because if there
are a large number of non-responsive nodes, the ping agent can take a
long time to complete (one second per non-responsive node or 10 second
timeout per node with 10 parallel tasks). This should more properly mark
nodes as DOWN.
