> 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
