Bug#959022: No need to be RC

[Thomas Goirand <zigo@debian.org>]

Hi,

With the correct options as per above (message #42), I was able to get
Cinder to work correctly with the QoS for I/Os. So I've lowered the
severity, as this package works correctly.

So I don't see this as a "grave" bug by the definition of our BTS,
though that being said, I'd very much would love to have the options
activated by default, or any other workaround, to make it easier for our
users, be included in Bullseye.

At the bare minimum, we need to document this, maybe in the release
notes for Bullseye.

Cheers,

Thomas Goirand (zigo)
