prepare 3.2.2 release (#191)

* Some changes from code review.

* Fixed instanceId

* Updates from PR review.

* Added version and flagVersion, if available

* refactor(LDClient, LDConfig): changes for PR

* refactor(LDClient): changed isInternetConnected behavior for PR

* refactor(LDClient): removed async getForMobileKeys and wait seconds version, replaced with method that returns requested instance

* Bugfix/timber cleanup (#92)

Relates to #60

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.

* Fix crash when example app is backgrounded twice.

* Add security provider update mechanism using Google Play Services to
attempt a provider update when TLSv1.2 is not available.

* Shared Preferences Fix for Multi Environment (#94)

* fix(SharedPreferences): added more SharedPreferences first time migration and differentiated SharedPreferences by mobile key

* fix(UserLocalSharePreference.java): added missing mobileKey additions to getSharedPreferences, cleaned up debugging code

* Fix edge cases in how multi-environment handles connection changes.

* fix(UserManagerTest.java): incorrect number of arguments to UserManager instantiation in unit test

* Remove line of testing code accidentally left in and refactor shared
preferences migration to make future migrations easier.

* Final fixes to store migration. Should be fairly future proof.

* Fix issue with primitive variation calls always returning null if fallback is null.

* Remove CircleCI V1 config file. (#97)

To prevent floating point errors in flag version comparisons.

* misc cleanup

* rm debugging

* add eval reason data model classes

* misc fixes

system that holds all the information on a flag to prevent issues
arising from unsynchronized separate stores for flag meta-data and
values.

* add methods to get value with explanation; refactor existing variation methods

* 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.

* 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.

This caused a race condition in repeated stream restarts that could put the SDK in a bad state.

* Change LDAwaitFuture to not treat zero timeout as unlimited timeout

Treating a timeout of zero as unlimited caused a change in behavior when initializing the SDK. This update restores the behavior init had when zero was passed as the timeout argument from pre-2.8.0. Also improves handling of spurious wakeups, and includes test cases for LDAwaitFuture.
