MINOR: trace/cli: parse the "level" argument to configure the trace verbosity

Browse Source 
The "level" keyword allows to indicate the expected level of verbosity
in the traces, among "user" (least verbose, just synthetic info) to
"developer" (very detailed, including function entry/leaving). It's only
displayed and set but not used yet.
