Introduce AlternativeServiceInfo.
* Introduce AlternativeServiceInfo and use it instead of AlternateProtocolInfo
in HttpServerPropertiesImpl.
* Change language in method and variable names and comments to consistently talk
about alternative service instead of alternate protocol (except for threshold
related occurrences).
* Update HttpServerPropertiesManager to save by key "alternative_service"
instead of "alternate_protocol", while still being able to read old
preferences.
* Add TODO(bnc) at a couple of places.
