Allow to configure export button props from list component and global admin

Is your feature request related to a problem? Please describe.

We currently need to change the default export max result from 1000 (defined here) to 5000 globally on the app.

To do so, we have first to create custom List and ListActions components:

const ListActions: FC<ListActionsProps> = ({ filters, ...props }) => {
  const {
    sort,
    filterValues,
    exporter,
    total,
  } = useListContext(props);
  const resource = useResourceContext(props);
  const { hasCreate } = useResourceDefinition(props);

  return useMemo(
    () => (
      <TopToolbar>
        <FilterButton
          filters={Array.isArray(filters) ? filters : [filters]}
        />
        {hasCreate && <CreateButton />}
        {exporter !== false && (
          <ExportButton
            disabled={total === 0}
            resource={resource}
            sort={sort}
            filterValues={filterValues}
            // The only thing we want to override is that part.
            maxResults={5000}
          />
        )}
      </TopToolbar>
    ),
    [
      exporter,
      filterValues,
      filters,
      hasCreate,
      resource,
      sort,
      total,
    ],
  );
};

export const List: FC<ListProps> = ({ children, filters, ...props }) => (
  <ListBase {...props}>
    <ListToolbar
      filters={filters}
      actions={<ListActions />}
    />
    <Card>
      {children}
      <Pagination />
    </Card>
  </ListBase>
);

Then, we have to replace the vendor List usage by our local one on each list resource we define on our project (nearly 15 for our case).

I see two main drawbacks with that:

1. This is cumbersome. We have now 50 lines of custom component just to change one number prop.
2. By using a custom one, we lose the benefit of simply use the provided vendor list and its furthers update because of the override.

Describe the solution you’d like

The ability to define the exporter option directly to the List:

<List
  export={{
    maxResults: 5000,
  }}
>

Or globally using the Admin component:

<Admin
  export={{
    maxResults: 5000,
  }}
>

Describe alternatives you’ve considered The alternative is already described by the problem section.

Additional context N/A

Maybe is not a crazy idea to add maxResults as an optional prop to ListActions component and pass it to the ExporButton. So one has to pass <ListActions maxResults={5000}> to a List component

The react-admin code is more complex because we have to maintain backward compatibility with previous versions. You only have one version to manage.

Anyway, let’s agree to disagree. You want to write less code, we want to avoid complexity, and these two objectives can’t meet in this feature request. Considering that your problem already has a solution, I suggest we leave it here.
