Tracing team is going to deprecate single tenant mode and force security in multi tenant mode.

That will affect this config:

https://docs.openshift.com/service-mesh/3.0.0tp1/traces/ossm-distr-tracing-assembly.html

And 2.X configuration.

There is not a timeline for this change (I guess it would be deprecated first)
