- "api trace on" from CLI should spit out when a control plane client is connected as a warning
- possibly spit out same message whenever someone connects to CLI (ie if you are in the CLI and plan to do anything other than SHOW commands, you should know if a control plane client is connected)
- Either extend "show api client" or add "show api status" so you know if api trace is on or off
- in CLI give more informative message than "ERROR: -1" if "api trace save foo" fails.
