This would apply to any type of cluster that uses the galera strategy while setting the nics on a create call.

    Fix MariaDB clusters failing with TypeError

    This would apply to any type of cluster that uses the galera strategy
    while setting the nics on a create call. When we called cast to set()
    the object was a list of lists. The set method can not has a list so
    this was causesing a unhashable error.

    The change is to make the instance_nics a list of strings (what we
    originaly expected) to resolve this issue.
