Motivation

Supports the mim task.

Modification

The main changes are as follows:

1. Addition of mim task processor (implemented based on entry point)
2. support for arguments not parsed in context

The minor changes are as follows:

1. Removal of ckpt hook and integration with reporter hook (interface change in ray 2.x)
2. Removal of ray train ddp trainer

The reason for the implementation of the second minor change is as follows:

1. Removal of dependency on ray train
2. Determined that the usability of the cfg table is decreased with the display of train loop config
3. Thought that ray train was too large for the desired function
4. Ray ddp trainer changed paths voluntarily
5. Need for sharing metrics between workers."

Based on the current implementation, I don't think it's necessary for BaseTask to have a parse_args interface. What do you think?
