Support for logging in ibm_db_dbi module

[bchoudhary6415]

You can enable logging in the ibm_db_dbi module to debug and trace activities. Logging can be directed to the console or a specified file.

To enable logging:

import ibm_db_dbi as dbi
#Log to console
dbi.debug(True)

#Log to a file (e.g., log.txt)
dbi.debug("log.txt")

#Stop logging
dbi.debug(False)

Calling dbi.debug(True) with Boolean True argument will output logs to the console.
Calling dbi.debug("log.txt") will log messages to the specified file (log.txt in this example).
Calling dbi.debug(False) with Boolean False argument will stop logging.
