Unit test failures when building 4.0.0 debian package

[Thomas Goirand]

When building the Debian package of Ironic (in Debian Experimental), I get 3 unit test errors:

FAIL: ironic.tests.drivers.test_seamicro.SeaMicroPowerDriverTestCase.test_set_boot_device_fail

    Try to standardize retrieval of an Exception's description

    Removes the use of exc.args[0] and exc.format_message() to retrieve
    message strings from exceptions in favor of using six.text_type() to
    maintain compatibility between python 2 and 3. Or through normal type
    coercion. Adds a __unicode__ method to make things more consistent.

    Closes-Bug: #1493233
