Description

GenericCli-based commands have a --verbose flag, which has two effects:

1. some subcommands print additional details
2. stack trace is shown in case of exception

I think (1) is more generally useful, while (2) is geared towards developers. To avoid making --verbose commands overwhelming for users in case of errors, I propose to split these two effects.

Possible solutions:

1. multi-level --verbose mode (allow specifying -v more than once to get more details)
2. introduce a new flag to enable the stack trace
3. only print the stack trace if exception message is not meaningful (eg. empty or "null")
