We should consider if it's feasible to move those functions making requests to .blob. endpoints into blob package.

It turned out ListDeletedBlobs doesn't exist in blob package swagger file. I'm afraid we have to use the one in datalake swagger. Now we need to check if any structs are defined in both packages. If so, how to deduplicate.
