Feat: Identity Verification iOS Implementation

[jennantilla]

Description

One Line Summary

Implement identity verification functionality to our Cordova SDK.

Details

Implement identity verification functionality to our Cordova SDK with JWT (JSON Web Token) that manage a specific User, their Subscriptions, and Identities, if enabled using OneSignal dashboard.

Motivation

The OneSignal Identity Verification feature only exists today for the Player model; we want to add this functionality to the User Model SDKs.

Scope

This PR only encapsulates changes to the Cordova wrapper and iOS bridge. A future PR will include Android implementation.

Testing

Manual testing

Testing was done with the iOS beta release v. 5.3.0-beta-01. Another round of testing will be completed when out of pre-release.

Checklist

Overview

• I have filled out all REQUIRED sections above
• PR does one thing
  • If it is hard to explain how any codes changes are related to each other then it most likely needs to be more than one PR
• Any Public API changes are explained in the PR details and conform to existing APIs

Testing

• I have included test coverage for these changes, or explained why they are not needed
• All automated tests pass, or I explained why that is not possible
• I have personally tested this on my device, or explained why that is not possible

Final pass

• Code is as readable as possible.
  • Simplify with less code, followed by splitting up code into well named functions and variables, followed by adding comments to the code.
• I have reviewed this PR myself, ensuring it meets each checklist item
  • WIP (Work In Progress) is ok, but explain what is still in progress and what you would like feedback on. Start the PR title with "WIP" to indicate this.
