    Fix docs for catalogd automatic invalidate flags
    
    --invalidate_tables_timeout_s and
    --invalidate_tables_on_memory_pressure do not need
    to be applied to impalads - they have no effect.
    
    I confirmed with Todd Lipcon and checked that the
    flag was only accessed in CatalogServiceCatalog,
    not either of the Impalad catalog implementations.
