TUN-8701: Simplify flow registration logs for datagram v3

To help reduce the volume of logs during the happy path of flow registration, there will only be one log message reported when a flow is completed.

There are additional fields added to all flow log messages:
1. `src`: local address
2. `dst`: origin address
3. `durationMS`: capturing the total duration of the flow in milliseconds

Additional logs were added to capture when a flow was migrated or when cloudflared sent off a registration response retry.

Closes TUN-8701
