1279979 Neutron TypeError when token invalid

When a neutron api-call is made, if the user's token is invalid, the
neutron client will return a type-error because no auth_url has been
provided.

TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

This TypeError should really be an
neutronclient.common.exceptions.Unauthorized instead, which will get
percolated up via a password-base authentication failure.

Don't lose AttributeError in API Wrappers

Instead of (implicitly) catching the AttributeError, and later
creating and raising a new one, we just re-raise the original
exception. This way all the information from the original is
retained, including the name of the actual object on which it
happened.

Always pass 'modal' context variable to workflow template

Workflow templates rely on 'modal' context variable to be true for
modal dialogs. Still, when rendering from WorkflowView,
this variable is missing. This causes e.g. absent cancel and close
buttons in flavor creating dialog (and also affects Tuskar UI).

Fixing issue with VXLAN network profile create

This encompases the fix for bug 1229808 which requires change in
arguments to the network_profile_create API to create overlay
profiles instead of vxlan profiles.
Additionally overlay profiles now have a new parameter called
profile sub_types which lets one specify which type of overlay
profile can be created. This adds the new parameter as well.

Closes-bug: #1229808

Action required status shows proper icon

Today, when user resize an instance and is waiting to confirm the
action, the status column shows a loading icon.

This fix will change it so that the status column will instead show a
action_required icon.
