(cherry picked from commit aa66db8)

* Replace cache per thread with global cache (#1393)

* global cache

* Replace the cache-per-thread with a global cache:
-Use rwlock to synchronize access to the cache.
-Replace the hash lookup of queries strings with rax to support safe access of multiple readers.
-When cache hit occurs, do (shallow) memcpy of the query AST along with reference count increase, and store the current execution params in the new AST copy.

* Fix memory leaks.
Bug fix: set AST in thread local storage after the shallow copy.

* Update comments in config files and number of threads in test_cache to fit the new cache design.

* Defending execution plans that are being cloned from evicted by another thread, by adding ref count.

* Change cache implementation so that cache item is copied within the cache get/set functions by using a callback. This ensures that cache item will not be freed when evicted from cache while it is cloned by another thread.
