[Pulp-list] Pulp now uses a configuration file for it's logging

[John Matthews]

I added in support for a logging configuration file for pulp.  

We can modify logging levels down to a specific logger, for pulp this generally means down to a specific python file.
This also works for grinder, gofer, qpid, and any other python modules that use the python logging.

I have a wiki page here with details:
https://fedorahosted.org/pulp/wiki/Logging

The path of the logging configuration file is specified in /etc/pulp/pulp.conf
[logging]
config: /etc/pulp/logging/basic.cfg

The directory /etc/pulp/logging can have multiple configuration files saved which make it easier to debug different areas of pulp.


This has been tested on Fedora and RHEL-5. (RHEL-5 presented a few issues, but they have been worked through and documented on the wiki).

I have found this helpful when running unit tests. nosetests does it's own configuration of python logging, this was causing our logs to be empty.
