Add dataset collection

[Yunnglin]

1. 注册数据集：
   • race
   • trivia_qa 不支持service
   • truthful_qa
   • mmlu
   • humaneval
   • general_qa
   • cmmlu
   • arc
   • hellaswag 不支持 service
   • bbh
   • ceval
   • gsm8k
   • competition_math
2. 支持指定URL模型服务评测
3. 支持数据混合评测，自定义collection schema

schema = CollectionSchema(name='math&reasoning', datasets=[
            CollectionSchema(name='math', datasets=[
                    DatasetInfo(name='gsm8k', weight=1, task_type='math', tags=['en', 'math']),
                    DatasetInfo(name='competition_math', weight=1, task_type='math', tags=['en', 'math']),
                    DatasetInfo(name='cmmlu', weight=2, task_type='math', tags=['zh', 'math'], args={'subset_list': ['college_mathematics', 'high_school_mathematics']}),
                    DatasetInfo(name='ceval', weight=3, task_type='math', tags=['zh', 'math'], args={'subset_list': ['advanced_mathematics', 'high_school_mathematics', 'discrete_mathematics', 'middle_school_mathematics']}),
            ]),
            CollectionSchema(name='reasoning', datasets=[
                    DatasetInfo(name='arc', weight=1, task_type='reasoning', tags=['en', 'reasoning']),
                    DatasetInfo(name='ceval', weight=1, task_type='reasoning', tags=['zh', 'reasoning'], args={'subset_list': ['logic']}),
                    DatasetInfo(name='race', weight=1, task_type='reasoning', tags=['en', 'reasoning']),
            ]),
        ])



task_cfg = TaskConfig(
    model='qwen2.5',
    api_url='http://127.0.0.1:8801/v1/chat/completions',
    api_key='EMPTY',
    eval_type=EvalType.SERVICE,
    datasets=['data_collection'],
    dataset_args={'data_collection': {
        'local_path': 'outputs/mixed_data_test.jsonl'
    }},
)
run_task(task_cfg=task_cfg)
