TEIIDDES-1971: Workaround for avoiding annoying errors in server log

* "Connection reset by peer" messages appear in the jboss log due to making
  a socket connection from the host heatbeat requests but never using the
  socket. Almost like the server is upset that we connected then closed!!

* The read socket stream normally returns the hostname of the server so
  this is logged along with a nice message, ensuring the socket is used
  before closing it.
