hyperv: Initialize target_iqn in attach_volume

The target_iqn is referenced before it is declared in the
case that an exception is encountered in _login_storage_target
or _get_mounted_disk_from_lun.  This causes the exception path
to cause an additional, misleading, traceback to be printed
after an exception is encountered.

This commit initializes target_iqn at the beginning of
attach_volume to avoid the traceback.

Fix divergence in attach_interfaces extensions

I pointed out in revision 7 of Ibe4cbd025700aa0d73a6d4d19fbf8f0005509428
that it we shouldn't use a different variable name in the identical code
shared between the v3 and v2 extensions, but that was never fixed before
merging.

Plug Vif into Midonet using Neutron port binding

Currently Midokura uses its own script (mm-ctl) to bind ports. However, support
for using this script is left out of the nova and neutron projects. This causes
confusion and makes deployments unnecessarily complicated for customers using
Havana. This fix is to change nova to properly use mm-ctl. Corresponding
changes will be submitted to devstack and neutron.

Fix status code of server's action confirm_resize for v3

The status code of confirm_resize should be 202, but it
returns 204 now. That because it returns HTTPNoContent
that overwrites the status code of decorator 'wsgi.response(202)'

And adds API samples for confirm_resize that used to test
the status code of confirm_resize.

Fix incorrect root partition size and compatible volume name

Remove compute_api_class config option

This option was deprecated in Havana and can now be removed.  Its only
use was for changing out the API class if cells was in use.
Technically, it used to be possible to configure an arbitrary compute
API class.  However, that would have been an unsupported setup, and has
been completely broken since 9f902c7e17249cf5af1504f31d80c0247a02fe20
anyway.

As a part of this change, the cell_type configuration option needed a
default value.  I set it to 'compute'.  My reasoning was that you would
have more compute cells than API cells, so might as well set it to the
more common case.

Port server actions unittests to V3 API Part 2

Ports the server actions unittests to test the V3 API.
This mostly involved CamelCase to camel_case changes
and adpating the URLs to point to the V3 API instead of
the V2 API.

It also includes
- Fixing a bug in the admin_password extension picked up by
  the tests where bad request data is not always handled properly
- Generate image ref urls that point to glance api rather than
  the nova api. This fits in with the decision to not port the images
  extension to the V3 API which is implemented here:
  https://review.openstack.org/#/c/40565/
- Moves admin password related tests to the admin password unittests
  test file as this functionality has been moved out from core.
