Can't dynamic import depending on where exec python

[imyutaro]

use_feature path is relative path where you exec python file, which is occurring bug. Change the way to specify use_feature.

    config = yaml.safe_load(
        """
    use_feature:
      # Path to TmpFeature1. In this case, this file saved as tmp.py, so path is .tmp.TmpFeature1
      - .tmp.TmpFeature1
      - .tmp.TmpFeature2
    feature_params:
      TmpFeature1:
        shift_b_to: 3
      TmpFeature2:
        const: 1000
    """
