Description of problem:
We found out that a special daemon needs to be started on a node to achieve really low latencies needed for Telco vRAN (See https://bugzilla.redhat.com/show_bug.cgi?id=1855447#c24 and later comments).
This daemon is only needed for real time nodes and so it is logical to enable it via NTO that is profile aware.
Due to customer requirements we request that as simple as possible stop gap solution is included into 4.6 even though we are past the feature freeze.
Upstream tuned was already enhanced with declarative service management plugin: https://github.com/redhat-performance/tuned/pull/293
$ for pod in $(oc get pods | grep tuned | cut -d ' ' -f 1); do echo $pod; oc rsh $pod ls /usr/local/bin; done
$ oc get clusterversion
