peerd: Don't use service tokens
Remove service tokens from the peerd API in favor of relying on a
combination of service IDs and remote DBus connection identifiers.
Also allow clients to call ExposeService on previously exposed services,
treating following calls as updates rather than errors. This simplifies
client implementations dramatically by allowing them to be agnostic to
the previous state of their service.
To do this, expose the connection_name in libchromeos's
DBusServiceWatcher.
