use `glog.info(...)` but this function is not made to be wrapped because
the underlying mechanism use a fixed call trace length to determine
where the log has been emited.
This results is having `logs.go:49` in the logs which is in the body
of the wrapper function and thus useless.
Instead use `glog.infoDepth(1, ...)` which tells the underlying mechanism
to go back 1 more level in the call trace to determine where the log
has been emitted.
