refactor!: Add EventHandler + Combine #29

Closed fabriziodemaria closed 9 months ago

fabriziodemaria commented 9 months ago

This PR

Removes event APIs at the client level (will be re-introduced when multiple clients/providers are supported)
Adds an EventHandler implementation that Providers can use to emit events (a FeatureProvider now extends the EventPublisher protocol)
Adds Combine as the API for eventing

Notes

Following patterns implemented in the Kotlin SDK as much as possible, for consistency

Follow-up Tasks

Add setProviderAndWait function in OpenFeatureAPI
Events should contain more metadata than just their type
Introduce ProviderStatus as an entity separated from ProviderEvent (also for Kotlin)
