[FEAT] Allow running transmission with custom IO priority (ionice)

Wanted change

I would like to be able to set a custom (in my case, lower) IO priority for the transmission process.

Reason for change

Serving torrent files can be quite an IO demanding task, specially on mechanical drives as due to the fragmented nature of torrents, seeking is very likely to occur in large amounts. This can make transmission a quite disruptive workload to run next to others.

Setting a lower IO priority (higher IO niceness value) can potentially help with this.

Proposed code change

We could allow users to define IONICE_CLASS and IONICE_LEVEL environment variables, which could be used as arguments to ionice's -c and -n in the /etc/s6-overlay/s6-rc.d/svc-transmission/run script. Alternatively, a oneshot service could also be used to ionice the transmission PID after it has started.
