Add missing indexes back in from 152

Migration 152 lost indexes on upgrade. This was fixed in migration 194
and 212 but one index is still missing on the migrations table.

This patch ensures the indexes are present on downgrade of 152 to be
consistent and also adds the missing index back in with a new migration.

Translate more REST API error messages

There were a few exception messages that were not being
translated because they were being wrapped and modified
before being turned into wsgi.Fault objects by
FaultWrapper. This adds some translation handling to
the FaultWrapper so we can get these messages localized
to the client's language specified in the Accept-Language
header.

Additionally adds a test to verfiy FaultWrapper is
translating any exception messages that can be.

Move required keymgr classes out of nova/tests

Currently the Nova default keymgr implementation tries to
import classes from nova/tests. This could be a very bad
thing for production deployments which may not include
code from nova/tests.

This change moves two required modules (single_key_mgr and
mock_key_mgr) into the nova/keymgr tree.

Wire in ConfKeyManager._generate_hex_key!

Rename _get_hex_key to _generate_hex_key so that this
key manager works with the super class it extends.

In making this change we also need to initialize the hex key
in the constructor before initializing the super class. Not
doing so causes test failures.

Don't use sudo to discover ipv4 address.

Running unit tests on a plane (with no network) and I recently
discovered that the Nova unit tests were prompting me for sudo.

A quick look showed the following command being executed:

 nova-rootwrap /etc/nova/rootwrap.conf ip -f inet -o route show

This patch updates utils.get_my_ipv4_address() and
the private _get_ipv4_address_for_interface function so they run
commands without using sudo.
