[Doc Source]: upgrade --set-args argument invalid

Are you reporting an issue with existing content? On linked page it is an advice to use kubectl mayastor upgrade command with --set-args , but this argument is invalid. Tried for both 2.7.0 and 2.7.1 kubectl-mayastor extension.

https://openebs.io/docs/user-guides/replicated-storage-user-guide/replicated-pv-mayastor/additional-information/performance-tips

./kubectl-mayastor upgrade -n openebs --set-args 'io_engine.coreList={2,3}'
error: unexpected argument '--set-args' found

  tip: a similar argument exists: '--set'

Usage: kubectl-mayastor upgrade --namespace <NAMESPACE> <--registry <REGISTRY>|--allow-unstable|--dry-run|--skip-data-plane-restart|--skip-single-replica-volume-validation|--skip-replica-rebuild|--skip-cordoned-node-validation|--skip-upgrade-path-validation-for-unsupported-version|--set <SET>|--set-file <SET_FILE>>

For more information, try '--help'.

what is the correct command?

btw. I did:

kubectl-mayastor upgrade -n openebs --set 'io_engine.coreList={2,3}'

and job completed:

but io_engines are still running on 1,2 cpus as before any changes.

I had also did helm upgrade with:

io_engine:
    coreList: [2,3]

and also no change.

I did also kill -9 io_engine pid and it was also recreated on 1,2 cpus.

So not sure if that setting is working at all, maybe should just keep defaults 1,2 and isolate these cpus.
