nit: since these are all manager specific, could you change those event_type
names to be HTPP_SERVER_PROPERTIES_MANAGER_*

Do you feel strongly about adding a MANAGER_ suffix?
The names are getting rather long. Some of the events are not named exactly
after the classes. E.g. We have HTTP_STREAM_JOB_CONTROLLER rather than the full
class name HTTP_STREAM_FACTORY_[IMPL_JOB]_CONTROLLER. We might in the future add
NetLog events in HttpServerProperties and group them together with these. My
preference will be to keep the names short while not introducing ambiguity.

Acknowledged. Okay, sounds like you have considered this. Yeah, I was thinking
that we  might will add NetLog events for HttpServerPropertiesImpl, and we might
want to differentiate or aggregate the NetLogs from impl and manager.
