Run mysql client inside mariadb container

[rimi-itk]

Updates the itkdev-docker-compose sql:connect command to run mysql inside the database container rather than assuming we have mysql installed on our local machine¹:

Before:

$ itkdev-docker-compose sql:connect
mysql --host=0.0.0.0 --port=53661 --user=db --password=db db
$ $(itkdev-docker-compose sql:connect)
ERROR 2026 (HY000): TLS/SSL error: SSL is required, but the server does not support it

After:

$ itkdev-docker-compose sql:connect
docker compose exec mariadb mysql --user=db --password=db db
$ $(itkdev-docker-compose sql:connect)
Welcome to the MariaDB monitor.  Commands end with ; or \g.
…

Furthermore, a new command, itkdev-docker-compose sql:cli, is introduced. This command allows us to easily drop into a MySQL session:

$ itkdev-docker-compose sql:cli
Welcome to the MariaDB monitor.  Commands end with ; or \g.
…

or send SQL commands to the database:

bash-5.2$ itkdev-docker-compose sql:cli <<< 'SHOW TABLES' 
Tables_in_db
actions
advagg_aggregates
…
