Method finalize

vm-migration/src/context.rs:181–204

Finalizes the metrics and returns a [`CompletedMigrationContext`]. This should be called right after the completed migration was acknowledged by the receiver. From now on, the metrics are considered finalized and should not be modified. They can be stored for further analysis. # Arguments - `state_dur`: The time needed to aggregate the final VM state (i.e., snapshotting it). - `send_state_dur`:

        self,
        state_dur: Duration,
        send_state_dur: Duration,

    /// - `complete_dur`: The time of the completion request. This includes
    ///   resuming the VM (if it was running before the migration).
