[hyeonLewis]

• Add query APIs for KIP113, KIP149.

1. KIP113

   • klay_getBlsInfos: Returns all registered BLS records in SImpleBlsRegistry contract (KIP113)

2. KIP149

   • klay_getAllRecordsFromRegistry: Returns all registered records in Registry contract (KIP14)
   • klay_getActiveAddressFromRegistry: Returns active address in Registry contract if exists

Any suggestions for improvements are welcome.
