-----------------------------------

             Summary: AdminService should avoid writing file in case just read instance status
                 Key: KARAF-3075
                 URL: https://issues.apache.org/jira/browse/KARAF-3075
             Project: Karaf
          Issue Type: Improvement
            Reporter: Freeman Fang


For an instance, admin:list will write underlying cfg file 9 times for each instance, that
said, if we have 3 child instance with 1 root instance, "admin:list" will cause 36 times file
write which is a significant performance lost as well as more chance to corrupt the cfg file.

For some operations in AdminService like get***Port, getInstance, getStatus, which are read-only
operations, we should avoid writing back to the cfg file after read
