Update git submodules

* Update neutron-lib from branch 'master'
  to 87d67dd3a93c208e8d2c7efb4e7c28942008a7ce
  - Merge "Service role is now considered as the one who can change project_id"
  - Service role is now considered as the one who can change project_id

    Previously with [1] new property "can_set_project_id" was added to the
    context.Context object but it was only True for the admin users
    (is_admin=True) and if "_can_set_project_id" parameter was True
    (configured via policy rules or passed directly to the __init__ method.

    It had to be like that because "_is_service_role" wasn't defined properly
    in the __init__ method and context.Context object wasn't able to be
    created with "self.is_service_role" used in the "can_set_project_id"
    property.
    Due to that in the neutron_lib.api.attributes._validate_privileges
    function it had to be explicitly checked if context is service role.

    Now, as _is_service_role is defined properly in the
    context.Context.__init__ method, it can be checked in the
    "can_set_project_id" property and
    neutron_lib.api.attributes._validate_privileges function can only check
    if Context.can_set_project_id == True to allow changing project_id of
    the resource.
