Details

Bootstrapping a database for SQL tutorials uses the old approach:

• https://www.tarantool.io/en/doc/latest/how-to/sql/sql_tutorial/#initialize
• https://www.tarantool.io/en/doc/latest/how-to/sql/improving_mysql/ (step 13)

We can use a new config instead and connect to an instance using tt.
