[SPARK-24029][core] Set SO_REUSEADDR on listen sockets.
This allows sockets to be bound even if there are sockets
from a previous application that are still pending closure. It
avoids bind issues when, for example, re-starting the SHS.
Don't enable the option on Windows though. The following page
explains some odd behavior that this option can have there:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms740621%28v=vs.85%29.aspx
I intentionally ignored server sockets that always bind to
ephemeral ports, since those don't benefit from this option.
