Allow selecting the rclone command (#11)

So far, the chart is restricted to [rclone
copy](https://rclone.org/commands/rclone_copy). This PR allows the
command to be set (e.g. to invoke [rclone
copyurl](https://rclone.org/commands/rclone_copyurl)).

`copy` is retained as the default command to avoid introducing a
breaking change.
