          BUG#28706307: CHARACTER SET OF ENUM DATA TYPE IS NOT AVAILABLE AS PART OF OPTIONAL METADATA
      		 
          BUG#28774144: MYSQLBINLOG --PRINT-TABLE-METADATA SHOW WRONG INFO ABOUT DEFAULT CHARSET

      And also create a function virtual binlog_type_info() for field which contains relevant metadata (like binlog_type(), signnness , charset , geom_type)
      For example 

         uchar m_type_code;     // according to Field::binlog_type()
      		 
        /**
      		 
           Retrieve the field metadata for fields.
      		 
        */
      		 
         uint16 m_metadata;
      		 
         uint8 m_metadata_size;
      		 
         binlog_signess_t m_signess;
      		 
         CHARSET_INFO *m_cs; // NULL if not relevant
      		 
         TYPELIB *m_enum_typelib; // NULL if not relevant
      		 
         TYPELIB *m_set_typelib; // NULL if not relevant
      		 
         uchar m_geom_type; // Non-geometry fields can return 0

      Usage:-
      This functionality will be later used to implement MDEV-19708
      binlog_type_info() function will be used in pluggable datatypes implementation
