I want `rclone` tested and evaluated

[mblomdahl]

I am struggling with mc mirror to sync multi-TB buckets from S3 to MinIO storage, with AWS as source it mostly seem to work but with B2 the sync progress in staggeringly slow (barely usable). The main problem seem to be server-side interruptions to transfers, yielding "http: ContentLength=x with Body length x-n [bytes received]" errors. Installing rclone and configuring it to do the heavy lifting, it might be a way forward.
