    Attachment: SOLR-9633.patch

Thanks Yonik and Michael for the reviews. This patch wrap all updates to ramBytes in the put() method with the check as requested. I'll commit shortly.

Michael, to your comment on this working only with Accountable, the example configurations specify this parameter only for filterCache so I feel it is unlikely that users will try to use FastLRUCache with maxRamMB for something else. But I'll make sure to include this point in the reference guide when documenting this feature.

> SOLR-7372 added a maxRamMB parameter to LRUCache to evict items based on memory usage. That helps with the query result cache but not with the filter cache which defaults to FastLRUCache. This issue intends to add the same feature to FastLRUCache.
