Add from_model_name in Engine

[harimkang]

Summary

Fix CVS-135466

It is not easy or possible to launch the model training using Python API with the given 1) data_root, 2) model_name, 3) task_type, 4) configuration overridings

So for now, Add Engine.from_model_name classmethod.

from otx.engine import Engine

model_name = "efficientnet_b0_light"
data_root = "tests/assets/classification_dataset"
task_type = "MULTI_CLASS_CLS"

overriding = {
    "data.config.train_subset.batch_size": 2,
}

engine = Engine.from_model_name(
    model_name=model_name,
    data_root=data_root,
    task=task_type,
    work_dir="otx-workspace-test-1",
    **overriding,
)

assert engine.datamodule.config.train_subset.batch_size == 2

However, we're still having trouble overriding the configuration provided by Auto-configuration without using from_config or from_model_name, so 'll be thinking about how to improve this.
