Change the place where we set the defaults for node ping
and node status interval. This problem manifested itself
by the node ping interval being 0 when it was set to
the default.
This makes two changes:
1. Invalid ping values, and ping timeouts will not
allow VK to start up
2. We set the default values very early on in creation
of the node controller -- where all the other values
are set.
