PS3, Line 28: allow_tuple_caching

The way I see it working is:
1. if allow_tuple_caching is false, then enable_tuple_caching is always false
2. if allow_tuple_caching is true, you can set enable_tuple_caching

Enable_tuple_caching is a query option. The frontend checks for 
enable_tuple_caching before running the TupleCachePlanner.

TupleCacheNode instances will not be created unless both allow_tuple_caching 
and enable_tuple_caching are true for a query.
