Staging branch for next major release 3.0.0 (#161)

* Separation of API, State, and Side Effects (#160)

* Separation of API, State and Side Effects. Largely left tests alone except for adding a couple and adjusting setup to accommodate changes.

* Use consistent nullability pattern so we aren't converting between empty string and null with identifiers.
Added proper deserializing of the profile attributes store property

* There is indeed a better way to do that

* Renamed some of the new classes and added new tests for them

* Doc blocks, minor cleanup, naming conventions

* Fix nullability test
Don't need immutable profile to expose attributes, but would be good to expose single attribute getter

* First round of PR comments

* missed another arg label

* Refactor singleton service initializers (#172)

* Convert SystemClock to class

* These shouldn't have been mocked in this test class, its masking a bug.

* Remove unnecessary, slightly risky, object initializers in core.

* Restore system clock to object -- I take it back, we don't have to get rid of objects, just have to be more particular about using object initializers.

* KLog can be a singleton object, no risk there.

* This simple fix would take care of the issue, but i still don't love KlaviyoApiClient being a singleton object that can hit an unrecoverable exception in its initializer...

* Found a balanced solution for KlaviyoApiClient -- converting this to a class was complicated by the inner class, and besides it works well as a singleton. The initializer was the real problem, so I extract the listeners from the initializer and created a startService method. This is safe to run multiple times if the SDK is re-initialized.

* Prefer this way: we don't need to wrap any of the code in this method body except the methods that are themselves protected anyway

* Forgot to add back starting the service in these tests' setup

* Naming convention things

* First shot at a pre-init buffer for failed operations. Needs tests

* Added test of in-memory slate

* I don't like import *

* Added comments, logging, and wrapped the retry operations in safeCall

* Trivial: move error logging out of exception class. Now that we wrap all SDK functions in safeCall, it is more straightforward to log from there.

* Allow ONLY handlePush to be buffered

* Remove unused test

* keep 3.0 version increment

* don't add this back

* never trust github

* Update versions.properties

 This document provides guidance on how to migrate from the old version of the SDK to a newer version. 
 It will be updated as new versions are released including deprecations or breaking changes.
 
+# 3.0.0
+
+### Improvements
+- The Klaviyo Android SDK now automatically tracks changes to the
+  user's notification permission whenever the app is opened or resumed.
+- Additionally, the SDK will now hold the push token internally after you `resetProfile`
+  and automatically attach the token to the next profile. This is a change from past behavior where the token
+  would need to be explicitly set again after resetting.

+### Breaking Changes
+- The `ProfileKey` options deprecated in `2.3.0` have been removed
+- `Klaviyo.lifecycleCallbacks`, deprecated in `2.1.0` has been removed

 ## 2.3.0 Deprecations
 #### Deprecated `ProfileKey` objects pertaining to identifiers
