Extension installation request: YAML

[boumanb]

ISSUE TYPE

• Feature request

SUMMARY

Adding the ext-yaml https://pecl.php.net/package/yaml PHP extension to Devilbox by default so that one can use it without having to install it each time a docker-compose down has been run. I'm aware of the fact that running docker-compose stop instead of docker-compose down will result in not losing the installation of a particular extension but this one seems quite viable to be added by default.

I've looked #263 and #107 and it I guess adding it to the image is the best way to accomplish the goal. Unless I've missed something in the documentation I think there isn't any more convenient way to install custom modules. If someone did succeed in doing so, please respond to this issue.

Thanks in advance.

Goal

Using the PHP YAML extension without having to reinstall it on every docker-compose down.
