Public bug reported:

Description
===========
At present requests to detach volumes from instances on down computes are accepted by n-api but will never be acted upon if the n-cpu service hosting the instance is down.

n-api should reject such requests with a simple 409 HTTP conflict.

Steps to reproduce
==================
* Attempt to detach a volume from an instance residing on a down compute.

Expected result
===============
Request rejected by n-api

Actual result
=============
Request accepted but never completed

Environment
===========
1. Exact version of OpenStack you are running. See the following
  list for all releases: http://docs.openstack.org/releases/

   Master

2. Which hypervisor did you use?
   (For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)
   What's the version of that?

   libvirt + QEMU/KVM

2. Which storage type did you use?
   (For example: Ceph, LVM, GPFS, ...)
   What's the version of that?

   N/A

3. Which networking type did you use?
   (For example: nova-network, Neutron with OpenVSwitch, ...)

   N/A
