* SOLR-9886: Add a 'enable' flag to caches to enable/disable them

> There is no elegant way to turn off caches (filterCache, queryResultCache
> etc) from the solrconfig. When I tried setting size and initialSize to zero,
> it resulted in caches of size 2. Here is the code that overrides setting zero
> sized cache.
> https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/search/FastLRUCache.java#L61-L73
> Only way to disable cache right now is by removing cache configs from the
> solrConfig, but we can simply provide an attribute to disable cache, so that
> we can override it using a system property.
