> Currently, when we access a container's logfile (via /ws/v1/node/containerlogs/) we can
only get the full content, not a specified range.
> Support for the Range: header would improve this, special when dealing with big files
that need to be tailed or streamed, i.e.:
> {code}
>     curl -H 'Range: bytes=10240' \
>       http://node:8042/ws/v1/node/containerlogs/container_XXX/stdout
> {code}
