ActionCache is used to store a mapping from CASID to CASID. The current
implementation of the ActionCache can only be used to associate the
key/value from the same hash context.
ActionCache has two operations:
putto store the key/value andgettolookup the key/value mapping. ActionCache uses the same TrieRawHashMap
data structure to store the mapping, where is CASID of the key is the
hash to index the map.
While CASIDs for key/value are often associcate with actual CAS
ObjectStore, it doesn't provide the guarantee of the existence of such
object in any ObjectStore.
