Change file list API to build whole JSON locally and return it instead of streaming

Description:

Currently the file list api below streams the JSON line by line:
artifactory/api/storage/<repo>/?list&deep=1&listFolders=1&mdTimestamps=1&statsTimestamps=1&includeRootPath=1

This can be an issue if the list is very big, and the stream is cut off, since replication fails. The next file list will have to start streaming from the beginning

Expected behavior:

Have some option for the API to build the full json locally and return the whole file at once instead of streaming the file.
