v7.4.0

🚀 Improvements

• added API with ability to access the database from other hermione-plugins. Example of usage can be found in docs;
• added "result_meta" extension point for html-reporter plugins;
• added ability to use connection to database on client side in gui mode from html-reporter plugins. This can be useful if the plugin needs to work with data from a database;
• added ability to merge all existing tables inside sqlite database. It means that if some plugin add new table to database then it will be automatically merge with another ones in case when tests run in individual chunks (using hermione-chunks)
