MDEV-4786 - merge 10.0-monty - 10.0

Fixed "check of testcases" failure.

Value of INFORMATION_SCHEMA.PLUGINS.PLUGIN_TYPE_VERSION was
pointing to incorrect address and could change after server
restart.

storage/innobase/handler/i_s.cc:
  Use proper plugin info pointer (struct st_mysql_information_schema
  instead of ST_FIELD_INFO[]).
