Code Issues Proposed changes

Update git submodules 

* Update os-traits from branch 'master'
  - Merge "Update SEV trait docs to avoid misleading people"
  - Update SEV trait docs to avoid misleading people
    
    Since the AMD SEV spec was approved for Stein, it was subsequently
    realised that a trait would not be sufficient for tracking SEV-capable
    compute hosts.  A resource class is also needed to track the inventory
    of "slots" available on these hosts, since the number of slots limits
    how many guests with encrypted memory can run concurrently.
    
    Therefore the design pivoted somewhat, and now
    trait:HW_CPU_AMD_SEV=required will not be the correct way to request
    SEV functionality:
    
      https://specs.openstack.org/openstack/nova-specs/specs/train/approved/amd-sev-libvirt-support.html
    
    For reference, the previous spec is here:
    
      https://specs.openstack.org/openstack/nova-specs/specs/stein/approved/amd-sev-libvirt-support.html
    
    Another lesson learnt from the Stein cycle was that it is not safe to
    assume that the work targeted for one cycle will actually land in that
    cycle, therefore it's safer for documentation of an in-progress
    feature to be transparent that it's in progress and not yet usable.
