[Improve][DataProxy] Modify the data format of metadata saved in the metadata.json file

Description

The parent issue:#10080

Currently, after DataProxy pulls the metadata from Manager, it directly saves the response message DataProxyConfigResponse returned by Manager in the metadata.json file, and re-parses the DataProxyConfigResponse object when loading the metadata.

It is found during use that every time the metadata is loaded, DataProxy needs to perform content checks, and it is not convenient for DataProxy to save additional information in the saved metadata. For this reason, in this PR, I added a new class InLongMetaConfig to save the metadata information of DataProxy specifically.
