    Make ComputeFilter verify compute-related instance properties
    
    This change adds checks in the ComputeFilter to verify compute hosts can
    support the (architecture, hypervisor_type, vm_mode) triple specified
    in the instance properties, improving support for heterogeneous clouds.
    
    Images can be marked with the architecture, hypervisor, and virtual
    machine mode they require, e.g.
    
    glance image-update --property architecture=x86_64 \
      --property hypervisor_type=kvm <image-uuid>
    glance image-update --property architecture=i686 \
      --property hypervisor_type=xen --property vm_mode=xen <image-uuid>
    glance image-update --property architecture=x86_64 \
      --property hypervisor_type=xen --property vm_mode=hvm <image-uuid>
    
    These properties are included in the request_spec part of the run_instance
    RPC message and made available to the ComputeFilter.  The ComputeFilter
    will only pass compute nodes that satisfy the specified properties.
    If no properties are specified, the ComputeFilter behavior is unchanged.
    
    Adding these checks to the compute filter seems consistent with its
    definition [1]:
    
    "ComputeFilter - checks that the capabilities provided by the compute
    service satisfy the extra specifications, associated with the instance
    type."
