Defining a plan entirely over environment variables

[sjiep]

As far as I can tell it is not possible in the current version to use the docker image without an explicit plan-id.yml file. This means for deployment you either a) have the YAML file has to be transferred to the target, or b) you have to build a custom docker image that has the config file copied into it.

It would be nice to the possibility define the entire plan using environment variables, such that that base image can be used without creating a custom variant of it. Any thoughts on this idea?
