YAML-formatted associative array of sysctl key/value pairs to be set
persistently. As a default we set pid_max to a high value to avoid
problems with large numbers (>20) of OSDs recovering. very large clusters

threads-max to a high value to avoid problems with large numbers (>20)
of OSDs recovering. very large clusters should set those values even
higher (e.g. max for kernel.pid_max is 4194303).
