Too many RC download buttons in API access page

[Akihiro Motoki]

In the API access page, we now see three or four "Download OpenStack RC" buttons.
It is nice if they are packed into a single menu.

    Move all RC download buttons under a single menu

    In the API access page, we now see three or four
    "Download OpenStack RC" buttons.
    This commit packs them into a single menu.

    To complete the goal, a new option called "table_actions_menu_label"
    is newly introduced to DataTable.

    Also the condition to disable an action dropdown menu is changed
    so that the action dropdown is not disabled when "multi_select"
    feature is not used in a corresponding table.
    Otherwise, the dropdown menu is always disabled and there is
    no way to enable it in a DataTable with multi_select=False.
