**Description**
Add support to store values of metrics in data diagnosis.

Take the following rules as example: 
```
    nccl_store_rule:
      categories: NCCL_DIS
      store: True
      metrics:
        - nccl-bw:allreduce-run0/allreduce_1073741824_busbw
        - nccl-bw:allreduce-run1/allreduce_1073741824_busbw
        - nccl-bw:allreduce-run2/allreduce_1073741824_busbw
        - nccl-bw:allreduce-run3/allreduce_1073741824_busbw
        - nccl-bw:allreduce-run4/allreduce_1073741824_busbw
    nccl_rule:
      function: multi_rules
      criteria: 'lambda label:True if min(label["nccl_store_rule"].values())/max(label["nccl_store_rule"].values())<0.95 else False'
      categories: NCCL_DIS
```
**nccl_store_rule** will store the values of the metrics in dict and save them into `label["nccl_store_rule"]` , and then **rccl_rule** can use the values of metrics through `label["nccl_store_rule"].values()` in criteria
