Add content-type input to override auto-detection

When uploading objects for file/tar agents, the content type was
always inferred from the file extension. This caused .tgz files
uploaded via source-type=file to be tagged as tgz, making rage
extract them as archives instead of placing them as single files.

The new content-type input lets callers explicitly set the object
content type (e.g., binary) to control how rage handles the file.
