TEIIDDES-2025  Fixes jboss 5 servers failing to display teiid connections

* Jboss 5 servers verify host connection using the web port which does not
  return any information on its input stream hence erroneously returing
  false

* Override the isHostConnected method in JBossServer7Util to continue
  querying the input stream for 7 servers and remove this querying for the
  default, ie. jboss 5fixed connection issue with AS 5/Teiid 7.7 server
