Allow setting max-size-bytes=0 to page immediately in order to preserve memory.

it should be trivial to have a page only address - <max-size-bytes>0</max-size-bytes> and there should be no implication for the size of the page file or page size. AFAIK there is no check when we page in, that we can fit a page in max-size-bytes, the only limits are on the page cache.

I think we should not warn or error out if the max-size-bytes == 0 and have it as a supported configuration.
