Review Comment:
   so if IIUC… 
   
   we can have otel and internal-tracing off, we can have just otel, or just 
internal-tracing, or we have have both on.  and these states don't impact the 
other…
   
   while the CEP has stated replacing internal-tracing as a non-goal, i am 
interested in vague sketching of how we could eventually do that.  the only 
functionality needed to carry forward is the `tracing on;`  output in cqlsh 
(any notion of sampling and querying system_traces is redundant if otel is 
being used).  then cqlsh tracing would ideally be done in-memory only (flushing 
system_traces is waste).
