ACCUMULO-1985 Allow the monitor to bind to all network interfaces.

Create a new configuration parameter that users can defined in accumulo-env.sh
that will, when starting the monitor process, override the value provided to the
--address option from the hostname to "0.0.0.0". We can't just put "0.0.0.0" in
conf/monitor as the scripts use each line in conf/monitor as the host to SSH to
and this would break starting the monitor on a remote host.

ACCUMULO-1599 Stop using /tmp wherever possible

  The only obvious remaining place I found was the Jetty temporary
  directories created by Hadoop MiniDFSCluster. These get cleaned up
  automatically when the tests pass and don't really offer much value
  for debugging test failures, so I don't consider it a high priority.
