Speed up warden for faster importing of large sql dumps.

1. Add the innodb options to the warden/environments/magento2.base.yml docker-compose YML file.
2. Restart warden environment warden env down && warden sync stop && warden env up -d && warden sync start
3. Import the .sql file with warden db import.
4. Remove options & restart warden enviornment once import completed.

Why these settings

• innodb_buffer_pool_size : Will cache frequently read data
• innodb_log_buffer_size : Larger buffer reduces write I/O to Transaction Logs
• innodb_log_file_size : Larger log file reduces checkpointing and write I/O
• innodb_write_io_threads : Service Write Operations to .ibd files. According to MySQL Documentation on Configuring the Number of Background InnoDB I/O Threads, each thread can handle up to 256 pending I/O requests. Default for MySQL is 4, 8 for Percona Server. Max is 64.
• innodb_flush_log_at_trx_commit : Not worried about data lost prevention steps.

Testing of performance:

With a 32GB .sql file from a Magento 1.x instance, importing with defaults would take days (avg 100KiB/s transfer rate) according to pv however with the above in place the import time eta of pv is now only 10 hours with an avg 750KiB/s transfer rate)

NOTE, Strict mode only set to OFF for other non performance reason.
