Review Comment:
   It needs to be discussed in different situations because this configuration 
file will be used by both the IDE launch and script usage:
   
   - If started using a script, take pd as an example, the output of the 
command line will be redirected to hugegraph-pd-stdout.log, and the logs 
defined within the log4j2.xml range will be obtained in hugegraph-pd.log (there 
will be a delay). In fact, the content of the hugegraph-pd.log log is basically 
the same as that in hugegraph-pd-stdout.log.
   - If started using an IDE, still using pd as an example, the command line 
output (pd runtime log) will be displayed in the RUN panel, and you will still 
get the logs within the range defined in log4j2.xml in the hugegraph-pd.log 
(there will be a delay).
   
   The conclusion is that if the script is used to start, the console appender 
is unnecessary. If the IDE is used to start, the console appender is meaningful 
(for timely observation of logs). Considering the delay in the generation of 
hugegraph-pd.log logs, it is recommended to keep the console appender.
