Client certificate
- support intermediate certificate. Currently, only supports client certificates directly signed by root CA.
- Currently, we took the following approach (caveats)
  - For Http2 and 1.1, prepare rustls::ServerConfig for each domain name and hence client CA cert is set for each one.
  - For Http3, use aggregated rustls::ServerConfig for multiple domain names except for ones requiring client-auth. So, if a domain name is set with client authentication, http3 doesn't work for the domain.
Make the session-persistance option for load-balancing sophisticated. (mostly done in v0.3.0)
- add option for sticky cookie name
- add option for sticky cookie duration
etc.
