    sql: introduce ADD CONSTRAINT CHECK statement
    
    This patch extends parser's grammar to allow to create CHECK constraints
    on already existent tables via SQL facilities.
    
    Closes #3097
    
    @TarantoolBot document
    Title: Document ADD CONSTRAINT CHECK statement
    
    Now it is possible to add CHECK constraints to already existent table
    via SQL means. To achieve this one must use following syntax:
    
    ALTER TABLE <table> ADD CONSTRAINT <name> CHECK (<expr>);
