Added logging to QMF console connections.

Warning if a broker can not be found, error if SASL authentication fails or other connection errors when connecting to an existing broker.  Default log level is ERROR.

qpid-printevents allows the log level to be set. It also allows the user to specify that a connection is required, in which case it terminates if a connection can not be established.

Examples: 

$ ./qpid-printevents --sasl-mechanism PLAIN nonexistent-broker

=> Not an error. Waits for the broker to be started.

$ ./qpid-printevents --sasl-mechanism PLAIN localhost
2010-12-22 17:07:18,365 ERROR Could not connect to broker localhost:5672 (None, 'No acceptable SASL authentication mechanism available')

=> Connection error condition in output - SASL authentication failed
   because user name and password are not supplied.

   But qpid-printevents keeps running, waiting for you to start the
   broker.

$ ./qpid-printevents --sasl-mechanism PLAIN --log-level critical

=> Connection error condition in output - SASL authentication failed
   because user name and password are not supplied.

   No output in this case, because the log level has been set to
   critical.

$ ./qpid-printevents --sasl-mechanism PLAIN --require-connection localhost
2010-12-22 17:11:03,791 ERROR Could not connect to broker localhost:5672 (None, 'No acceptable SASL authentication mechanism available')
Failed: ConnectionFailed - (None, 'No acceptable SASL authentication mechanism available')

=> Connection error condition.

   qpid-printevents terminates because --require-connection was specified.
