Nova ironic driver review update requests to p4

In https://review.openstack.org/#/c/111425/7/nova/tests/virt/...
...ironic/test_driver.py it was requested to change the way API
testing was conducted.  In doing this, some slight alterations
have been needed to ensure conformity.

handle invalid seamicro_api_version

If the value for seamicro_api_version is invalid, seamicro raises
an exception. Instead of the seamicro exception, this patch raises
an InvalidParameterValue exception instead.

Update nova driver's power_off() parameters

The nova driver's power_off() function received two new parameters
in commit c07ed15415c0ec3c5862f437f440632eff1e94df (nova).  The
in-tree drivers were all updated.  This updates the Ironic driver
and avoids a traceback during power off.

Set ssh_virt_type to vmware

Tests for set_boot_device and get_boot_device were incorrectly setting
the ssh_virt_type to vmware, so that it didn't get changed from the
original vbox value. This fixes it.

Add driver name on driver load exception

When non-DriverLoadError exception occurs during driver loading, it is
reraised, providing no information about driver that caused it. In this
patch such exceptions are wrapped in DriverLoadError with driver name
provided and reraised if driver is enabled.

Set PYTHONHASHSEED for venv tox environment

We're seeing frequent failures of the docs Jenkins job that appear
to be caused by the tox 1.7.2 upgrade and the migration to using
PYTHONHASHSEED=random.  This overrides the environment in the venv
testenv to set PYTHONHASHSEED=0 and allows docs to build
successfully.  Note that we want to run our tests with a random seed
if possible, so this avoids disabling it for the base testenv and
only uses non-random for the testenv used by Jenkins for doc builds.

Add support for creating vfat and iso images

This commit introduces support for creating vfat images
and iso images in ironic. Vfat images will be used for
passing information to baremetal node using virtual
media through OOB channel. Iso images will be used for
booting up baremetal nodes via virtual media.
