Pretty big change in this release!
Integrated the (originally go-flagz now dflag) dynamic flag library in fortio
(usable independently as fortio.org/fortio/dflag)
it gives a new flags debugging endpoint: http://localhost:8080/fortio/flags
and a new configmap directory; e.g; -config /etc/fortio and where you can change the loglevel flag dynamically
See dflag for more details on dynamic flags
