[MINOR] report list of supported pollers with -vv

During troubleshooting, it's often useful to get the list of supported
pollers but until now it was required to have a working configuration
first. Since the pollers are known before main() is called, let's list
them with the build options.

Also report the default MAXCONN setting.
