--enable-pprof command line flag is ignored

[viciious]

Beginning with at least 3.1.3 the enable-pprof flag doesn't seem to do anything if a config file is passed to the server. Here's the command line log:

./etcd --enable-pprof

2017-08-15 15:26:54.433050 I | embed: listening for peers on http://localhost:2380
2017-08-15 15:26:54.433238 I | embed: pprof is enabled under /debug/pprof
2017-08-15 15:26:54.433589 I | embed: listening for client requests on localhost:2379

./etcd --enable-pprof --config-file etcd.conf

2017-08-15 15:25:52.509596 I | embed: listening for peers on http://localhost:2380
2017-08-15 15:25:52.509885 I | embed: listening for client requests on 0.0.0.0:2379

AFAIK, there's no way to enable the pprof port via a config file.
