v4.0.0-alpha.2 — Apollo Client

#12450 876d070 Thanks @jerelmiller! - Remove TSerialized generic argument to ApolloCache. The ApolloCache base cache abstraction now returns unknown for cache.extract which can be overridden by a cache subclass.
#12450 876d070 Thanks @jerelmiller! - Remove the TCacheShape generic argument to ApolloClient. client.extract() now returns unknown by default. You will either need to type-cast this to the expected serialized shape, or use the cache.extract() directly from the subclass to get more specific types.
#12446 ab920d2 Thanks @jerelmiller! - Removes the defaultOptions option from useQuery. Use options directly or use the global ApolloClient defaultOptions.
#12442 c5ead08 Thanks @jerelmiller! - Remove the deprecated canonizeResults option. It was prone to memory leaks. As such, some results that were referentially equal when canonizeResults option was set to true no longer retain the same object identity.
#12442 c5ead08 Thanks @jerelmiller! - Remove resetResultIdentities option from InMemoryCache.gc(). This affected object canonization which has been removed.
#12451 77e1b13 Thanks @jerelmiller! - Default the TData generic type to unknown in all APIs that use a TData generic argument such as useQuery, client.query, etc.

#12451 77e1b13 Thanks @jerelmiller! - Default TVariables generic type to OperationVariables instead of any throughout the client in areas that did not yet have the default as such.
#12454 925548a Thanks @phryneas! - Fix up the 4.0 CommonJS build
