print statements in driver

[phartleyp]

otii_connection.py contains a print statement that looks like it was intended for debugging.

This print statement causes problems for command-line applications that print their own text to stdout, because it introduces random "Progress on ..." messages into application output.

The print statement should be removed, or possibly replaced with a logging output to a client-specific logger. If the message is logged (instead of printed) the application can control where and how to output it.

This has been removed in v1.0.9.
