GEODE-871: build-up of sockets in TIME_WAIT on locator machine

This change-set alters the client to abort its TCP/IP connection to
the locator by enabling SO_LINGER and setting the timeout to zero
before it closes the connection.  The Locator closes its connection
first, which puts it into TIME_WAIT.  The client then aborts the
connection, which cleans up the Locator's TIME_WAIT connection.

> The executeOnAllServers implementation contacts a locator in order to get the current set of servers.  This opens a TCP/IP connection to the locator, interacts with the locator and then closes the TCP/IP connection.  The connection is ending up in TIME_WAIT state though, indicating that the locator is usually initiating the close of the connection instead of the client.
> These TIME_WAIT TCP/IP connections can build up rapidly and cause the locator to run out of ephemeral ports.  That puts the locator out of commission until the connections are timed out by the OS.
