    Add functional test for AggregateMultiTenancyIsolation + migrate

    A bug was reported against Ocata where a non-admin user
    creates a server and the user's project is isolated to a
    set of hosts via the AggregateMultiTenancyIsolation filter.

    The admin, with a different project, cold migrates the server
    and the filter rejects the request because before change
    I195d389ac59574724a5e7202ba1a17d92c53a676 the cold migrate
    task would re-generate the RequestSpec using the request context
    which was from the admin, not the owner of the instance.

    Even though this is not a problem past Ocata, we did not have
    functional test coverage for this scenario so it is added here.

    This will also be used to backport the fix to Ocata to show
    the regression and fix in that branch.
