LOG.exception fails on Python 2.x when the exception content needs decoding

[Alessandro Pilotti]

The following example, generates an exception in openstack.common.module:

http://paste.ubuntu.com/8574082/

    from openstack.common import log as logging

    with open("unicode-content.txt", 'rb') as f:
        text = f.read()
    LOG = logging.getLogger(__name__)
    LOG.exception(Exception(text))

The calling code should be responsible for decoding the content before assigning it as the exception message, but nevertheless, the logging module should handle this gracefully and not raise an exception.

    Fixes unicode logging decoding issue

    Logging fails with an exception when unicode conversion of the message
    cannot be performed.

    This includes also Exception objects, where the exception message has
    an unknown encoding.

    The calling code should be responsible for handling the unicode encoding, but
    nevertheless, the logging module should handle this scenario and not raise
    an exception.
