…-todos

[User Model] Visual logging and other TODOs

[User Model] Session Manager

* Move IAM/Notification/Location to their own gradle modules. AndroidManifest/proguard has now been split across the 4 modules.
* Load modules dynamically using reflection within OneSignalImpl, falling back to "Misconfigured" versions if the modules weren't specified in the application.
* Make internal classes required by a OS module no longer defined as `internal` (but keep in internal namespace).

[User Model] Modularize IAM/Notification/Location

* local ID -> remote ID now get changed directly against the model. There is no longer an in-memory translation, which did not work in the event of an app restart.  Each operation now has a `translateId` method to drive updating their IDs.
* Rename `CreateUserOperation` to be `LoginUserOperation` and now has the ability to "identity" an existing user as the user being logged in, rather than always upserting a new user.
* Update `OperationRepo` and supporting executors to properly handle error conditions.
* Update `IOperationRepo.execute` to be `enqueueAndWait` which supports the change in behavior,,execution of an operation always happens on the background thread and does *not* jump the queue.
* Update operation executors to now ensure the model is in a correct state post-backend execution.

[User Model] New login process and operation repo updates

[User Model] Core Unit Tests

* Renamed/moved `iam` module to be `inAppMessages` module
* Renamed/moved `notification` module to be `notifications` module
* Renamed `sendOutcomes` to be `addOutcomes`
* Renamed `setTags` to be `addTags`
* Moved triggers to be within `inAppMessages` module

[User Model] Move and rename

* Add `TrackSessionStartOperation`
* Update executor to count sessions refresh device metadata on `TrackSessionStartOperation`

[User Model] Track Session Start

* Use SubscriptionStatus enum for subscription status across the codebase.
* IUserManager.subscriptions.push can no longer be null. If there isn't a push subscription a "dummy" one is now returned.
* Add `fallbackToSettings` parameter for `ILocationManager.requestPermission` and `INotificationsManager.requestPermission`
* Renamed `INotificationsManager.permissionsStatus` to `permission` and made it a simple Boolean.
* Added `INotificationsManager.canRequestPermission` as a flag to indicate when permissions can be requested.
* Added `ISubscription.addChangeHandler` to allow user to listen for changes to the subscription.

…ription-alignment
