sentry.tasks.cleanup should use logging instead of print

[23doors]

In distributed environments, adding sentry cleanup to cron is not a good enough choice anymore.

That's why it was better for us to run it inside celery task. All is peachy, but this task is printing a lot of crap to stdout while it should use logging instead. Like:

WARNING 2012-10-31 17:49:09,962 celery.redirected[log.py:238]: checking filters

Preferably allow logger parameter to it.

E.g.
def cleanup(days=30, logger=None, site=None, server=None, level=None,
project=None, resolved=None, logger=None, **kwargs):
print_info = logger.info if logger else sys.stdout.write

And in code, use print_info instead of print.
