Configure a memory_limit for scheduled tasks of a Laravel app on Clever Cloud

README.md

Problems

• some of my Laravel's scheduled tasks fail because the default memory_limit of PHP is too low
• running php -d memory_limit=xxx artisan schedule:run does not seem to have any effect
• there is no way to provide a custom php.ini for CLI-only on Clever Cloud

Solution

This patch adds a simple way to set memory_limit using a CLI_MEMORY_LIMIT environment variable. This new setting only applies when the Laravel app is booted from CLI (like when running php artisan ... commands) and have no effect on the memory_limit value in web context.
