[native] Implement persistent rust backup client

Summary:
ENG-6213 : Create long lived backup client

Implemented a native rust backup client that creates a websocket connection for logs, keeps it alive and retries when getting an error.

Test Plan:
Tested on Android and iOS:

• Started the backup handler -> checked the backup service logs for new websocket connection
• Waited a bit to make sure ping and pongs are handled correctly
• Killed the backup service and restarted it -> the connectino was restarted automatically
