We directly instruct the server to read from the local filesystem
in case the local_mode key is set.
There is now no need to upload the file in --local mode and a warning
is thrown accordingly.

```release-note
Now the mmctl bulk import process command in local mode supports processing an import file without actually uploading it to the server. Simply pass the file path to the import file and the server will directly read from it, and pass the --bypass-upload flag. There is no need to use the import upload command. NOTE: all of this is applicable only in local mode.

It was a good decision in hindsight to keep the public module as 0.x
because this would have been a breaking change again.
