Update git submodules

* Update os-traits from branch 'master'
  - Add COMPUTE_IMAGE_TYPE_* traits
    
    These are traits used to represent Glance image types that may be supported
    by a service such as nova-compute. Glance defines these types rigidly in
    their documentation:
    
      https://docs.openstack.org/image-guide/image-formats.html#disk-formats
    
    and thus they should be stable and standardized for use in placement
    queries.
