Bug Description

confirm_resize compute manager call should not require admin context.

From _delete() in compute_api, we're not passing an elevated context to confirm_resize when we try to delete instances in RESIZED.

The fix to bug 1056601 didn't fully address the issue.

    Fix use of elevated context for resize methods

    elevated contexts were being passed over RPC to confirm_resize,
    revert_resize, and finish_revert_resize methods. If those methods need
    to elevate context, they should do so themselves.

    There was 1 case (when deleting an instance in RESIZED) when we'd send a
    non-elevated context to confirm_resize(). This would fail because the
    migration_get() call there requires admin context and confirm_resize()
    on the manager side did not elevate the context itself.

    This fixes bug 1071600 and removes sending elevated contexts for these
    methods over RPC.

    (Ultimately we need some work to make the migration* DB API calls verify
    project_id vs requiring admin context..)

This is a tricky backport and probably should be fixed via just passing an elevated context in _delete

    Pass elevated context to confirm resize

    The actual fix for bug 1071600 is a bit too invasive to backport,
    so this is a simpler fix that only changes one line.
