Removing default log configuration and usage

This change removes the use of default logging settings in
kmip.__init__.py as well as the bundled logconfig.ini file. Logging
settings should be set by applications, not by underlying software
libraries. All demos have been updated to set their own logging
settings and to log at appropriate levels.
