Add accessor to retrieve LDClient specific UserManager. Iterate over all environments in PollingUpdater. Add environment argument to UserManager constructor, removing singleton and creating replacing init with newInstance static method.

…Manager may not be able to do the same so removed the environment from the constructor.

Cleaned up timber logging messages to use string formatting rather than concatenation. Log messages should remain the same as before.
Also replaced Log with Timber in the example app.

Added version and flagVersion retrieval from ping events if available

This reverts commit 69c1c9b.

* Changed shared preferences store system to user a single FlagStore
system that holds all the information on a flag to prevent issues
arising from unsynchronized separate stores for flag meta-data and
values.

* Abstract FlagStoreManager from FlagStore, new FlagStoreFactory class so manager can construct FlagStores of unknown type. Reformatted interfaces. Removed unused imports.

* Handle null case in allFlags, actually commit changes to UserManager.

* Hopefully fix edge cases in summary event reporting to pass testing.

* Hopefully fix edge cases in summary event reporting to pass testing.

* Simplify getFeaturesJsonObject as no longer using -1 as placeholder for null for variations.

* Make Flag non-mutable. Move GsonCache to gson package, move custom serializer/deserializers to classes in gson package and create one for PUT responses. Removed BaseUserSharedPreferences.

* Send summary event even if stored flag doesn't exist.

* Move sendSummaryEvent update code to UserSummaryEventSharedPreferences to synchronize to prevent data race on sending, updating, and clearing event store. Move SummaryEventSharedPreferences and UserSummaryEventSharedPreferences out of response package.

* Update SharedPrefsFlagStore to hold StoreUpdatedListener in weak reference. Fix various warnings.

* Migration code for upcoming flagstore.

* Remove couple of debug messages.

* Handle todos.

* Revert to old String behavior for allFlags, initialize WeakReference in SharedPrefsFlagStore.

* Better implementation of EvaluationReason serialization type adapter.

* Remove isUnknown argument from SummaryEventSharedPreferences methods. Use Runnable instead of Callable in UserManager to avoid useless return nulls. Rename FlagStoreFactoryInterface to FlagStoreFactory.

* Statically initialize Gson instance in GsonCache.

* Make Gson instance in GsonCache final on principle.
