Issue:
Add asynchronous execution support in Modin xgboost.predict
### Describe the problem
Current implementation of `predict` in Modin XGBoost can be improved by the next ways:

1. Exclude force partitions redistribution between nodes in Ray cluster.
2. Add asynchronous execution support by excluding blocking calls during execution.

-   * ``train``: `booster` and `evals_result` is returned using ``ray.get`` function from remote actor. Placement
