Middleware to switch the upload handler and use HDFSfileUploadHandler for document upload

What changes were proposed in this pull request?

Middleware to switch the upload handler and use HDFSfileUploadHandler for document upload. When the chunked_file_uploader and task_server config is enabled, the document uploads tries to use FineUploaderChunkedUploadHandler. Since user's don't upload large files in document upload's page (small json files with saved queries are uploaded), the chunked_file_upload implementation isn't needed. So adding a middleware to switch the upload handler in Documents upload page to HDFSfileUploadHandler even when the HDFS, S3, Azure FS might use the FineUploaderChunkedUploadHandler.

How was this patch tested?

Tested on mac, docker based system. Tested uploading a document concurrently during HDFS, S3, Azure file uploads.

Why are we adding a dedicated middleware only for this specific use-case? Can't we do this closer to the core document import code section?
