Persistent and optimized pageSize in Animals page

[saulyz]

This task depends on #193 (redux implementation).
The page content is populated via Redux data now. But after the user navigates away, the pageSize is not saved. When the user gets back to the page, pageSize defaults to the initial value and the view resets. This causes visual distraction and forces data re-fetch from the backend instead of using the previous state.

The filter values should also be saved for keeping the page state. (an upcoming task)

Possible page sizes (rowsPerPageOptions) should be extracted from PaginationRounded and moved to the App configuration.
