Enable more flexible infra plugins

[ragingdave]

So this isn't exactly a bug report but more of a feature request as I was looking to create a new plugin for example for redis, but I don't want to have to create a whole repo as well as maintain tags for each version of redis there has ever been or will be.

Is there a way to enable more flexible ways to handle this? perhaps decouple the version from being hard coded and allow a dynamic docker compose yml that could be env based as to what image to pull in? This way we'd only need to create tags when there's a major configuration difference instead of just creating a tag for the sake of creating a tag?
