😈 [Improvement Proposal] - Extend initialize function to include feature flags for alpha / breaking changes

[HarshRajat]

Proposal name

Create a way by which alpha can be integrated into stable version without breaking compatibility

Describe the Proposal

Create a way by which alpha can be integrated into Stable version without breaking compatibility via the use of feature flags.

Flow:

• Initialize user will have options.alpha.feature which will be an array of string constants (CONSTANTS.ALPHA.FEATURE.{feature_name}.
• This will enable us to merge alpha versions to stable without breaking compatibility as any alpha logic that breaks functionality is turned off but any read functionality is already live as soon as the feature is done.

Referring to this API: https://push.org/docs/chat/build/initialize-user/

Use Case

• Enables new features to be merged in stable as soon as they are done and elongates backward compatibility in most cases.

Current Limitations

• No solution exist to get current implementations of Push SDK to start supporting any breaking changes without breaking the version.
