Is possible to add plugins with additional dependencies?

[juangon]

From 1.4.x there is a new possibility for creating custom plugins by just adding them to a simple Dockerfile and create some Custom Resources (https://docs.konghq.com/gateway-operator/1.4.x/guides/plugin-distribution/).

My question is, if there are some additional dependencies (maybe some "resty.X") does this method still apply or we would need to create a custom kong-gateway image with that plugin as stated here? https://docs.konghq.com/gateway/latest/plugin-development/distribution/.

Is there a list with available dependencies when developing custom plugins that we can use out of the box?

Thanks very much!
