Update en_US message translations.

Fixes bug 1101587.

* nova/locale/en_US/LC_MESSAGES/nova.po: This "translation" was
woefully outdated, causing KeyError exceptions under a number of
circumstances for users of this particular locale when format
strings wound up containing incorrect substitution variables. This
change attempts to sync up the msgstr entries to match msgid given
this is the source language for the pot file. I did not see any
obvious instances where en_US should differ from C locale for these.

separate libvirt injection and configdrive config variables

This is mostly a refactoring so that if config drive is required,
variable lookup only needed for the injection case, is avoided.

There is a functional change here to make 'admin_pass' consistent
with the other variables in that the libvirt_inject_password flag
now does _not_ control whether the admin password is placed
in the config drive.

Default value of monkey_patch_modules is broken

The default value of monkey_patch_modules has not kept up with
the move of notifier to openstack.common

Without this change setting 'monkey_patch=True' in nova.conf
will cause runtime errors unless the monkey_patch_modules
is also specified pointing to the correct notifier

lxc: Clean up namespace mounts

5f697f64e5c445ba1b62c82d9167fd6b9c7256d2 introduced a regression
when using lxc containers with qcow2 and qemu-nbd.

When removing the rootfs from the host namespace, it would
terminate the qemu-nbd process as well. This would cause
the kernel too oops under Ubuntu 13.04. Since the underlying
device thtat the libvirt_lxc process disapears.

To get around this we just clean up the host namespace if the
instance is powered-on. When the instance terminates it will
teardown the whole container.

This fixes LP: #1115786

Adds original copyright notice to refactored files

Fixes bug: #1116586

The Hyper-V driver contributed for Folsom contains some refactored code
from the Diablo release contributed by Cloud.com.

Although the copyright notice remained in the "driver.py" file, it has
erroneously not been added to the new "vmops.py" and "vmutils.py" files
that contained some refactored code from the original contribution.

Remove strcmp_const_time.

This function was used with deprecated auth and is no longer used

Change forward_bridge_interface to MultiStrOpt

The config option specifically mentions it can be set multiple times
but it was accidentally set to a ListOpt instead of a MultiStrOpt.
