[FEATURE REQUEST] add morre hs options

[nyxnor]

Is your feature request related to a problem? Please describe.

These options were not included before because they are non essential and common users don't need. It is only necessary for high traffic onion services.

https://2019.www.torproject.org/docs/tor-manual-dev.html.en

• HiddenServiceExportCircuitID
• HiddenServiceMaxStreams N
• HiddenServiceMaxStreamsCloseCircuit 0|1
• HiddenServiceNumIntroductionPoints NUM

Discarded HiddenServiceNonAnonymousMode and HiddenServiceSingleHopMode because I don't like it.

Describe the solution you'd like

• HiddenServiceExportCircuitID: only one protocol, wont have an argument, if option is set, use it.
• HiddenServiceMaxStreams: requires the number of maximum streams
• HiddenServiceMaxStreamsCloseCircuit: depends on max streams, and if setting max streams, than of course you want to close circuits after reaching it, or I guess, I don't have access to a high traffic service.
• HiddenServiceNumIntroductionPoints: requires integer, from 3 to 20.

Describe alternatives you've considered
