Ideal Version of Enforcing Poetry Version

This issue is somewhat related to #111 and #112 . The concern is to solve issues with poetry itself, both the DockerFile and MakeFile contain a reference to a specific version of poetry. The ideal version:

> Running make environment for the first time would install a specific version of poetry (call it vX.Y)
> Running make environment on an existing environment would ensure the correct version of poetry is installed
> The docker container would use the correct poetry version in all cases
> Our linting or CI could include some verification that the lock file is generated for the correct version of poetry (I haven't looked deeply enough at the lock file to know how hard this would be).
