IF: SHiP changes to support IBC services (adding finality_data log)

[linh2931]

A new log finality_data is introduced to SHiP to stream finality related data. It is enabled by option --finality-data-history when starting a SHiP.

To fetch finality_data, use the new version of get_blocks_request:

struct get_blocks_request_v1 {
   uint32_t                    start_block_num        = 0;
   uint32_t                    end_block_num          = 0;
   uint32_t                    max_messages_in_flight = 0;
   std::vector<block_position> have_positions         = {};
   bool                        irreversible_only      = false;
   bool                        fetch_block            = false;
   bool                        fetch_traces           = false;
   bool                        fetch_deltas           = false;
   bool                        fetch_finality_data    = false;;
};

finality_data contains the following data:

struct finality_data_t {
   uint32_t     major_version{light_header_protocol_version_major};
   uint32_t     minor_version{light_header_protocol_version_minor};
   uint32_t     active_finalizer_policy_generation{0};
   digest_type  action_mroot{};
   digest_type  base_digest{};
};

A sample test run result looks like
