Update HttpServerProperties::*AlternateProtocol* interface.

* Rename SetAlternateProtocol, WasAlternateProtocolRecentlyBroken,
  ConfirmAlternateProtocol, ClearAlternateProtocol methods to
  *AlternativeService*.
* Rename SetBrokenAlternateProtocol to MarkAlternativeServiceBroken.
* Make MarkAlternativeServiceBroken, WasAlternativeServiceRecentlyBroken, and
  ConfirmAlternativeService take |alternative_service| instead of |origin|.
* Make SetAlternativeService take |alternative_service| instead of separate
  |protocol|, |port| arguments.  |alternative_service.host| is currently
  ignored.

This CL does not rename SetAlternateProtocolProbabilityThreshold and
GetAlternateProtocolProbabilityThreshold methods or
alternate_protocol_probability_threshold_ members, that will come later.
