Feature Request: Make package configuration easier with Recipes

Current Situation

Some packages (such as MariaDB, Apache, and NGINX) require configuration or special environment variables to work correctly with the Nix store + customer's devbox projects. For example -- MariaDB's default installation with Nix requires users to specify where the PID and SOCK file should be stored, and then pass those variables when starting and stopping mysqld.

Proposed Solution

Devbox should provide a way to create and share configuration for specific packages, and add this configuration when the developer installs the package. For example -- when setting up MariaDB, we can automatically set some default env variables that will be used when the developer activates their devbox shell.

This automatic configuration should be published in an open format, so developers can add Devbox configuration for packages as needed.
