Create new directive HiddenServiceExportStats.
Currently HiddenServiceExportCircuitID specifies the protocol. As we move towards exporting as much stats as we can, I think it's better to create a new directive(HiddenServiceExportStats) for the protocol only.
Also, I need some opinions on the directives.
- Create directive per stat(
HiddenServiceExport*), make all of them bound to the hidden service (inhs_service_config_t). - Create directive per stat, only 
HiddenServiceExportStatsbounds to the hidden service and others are global (inor_options_st). - Don't create directive per stat, Only one directrive 
HiddenServiceExportStats, bound to the hidden service, exports all.
