"log to pt_state directory" option for snowflake-client
My removal of default logging in 12922a232b was arguably rash: while obviously eventually we would have to stop logging by default, requiring a
-logoption with a path prevents writing to a log file that's inside the
pt_statedirectory, which, in sandbox situations, may be the only place the transport plugin is allowed to write. obfs4proxy just has a boolean option
-enableLoggingthat doesn't take a path, unconditionally writing to
pt_state/obfs4proxy.log. Perhaps something like that would be better, even if it's less convenient for development.
Maybe just add another flag,
-logToStateDiror the like
