Add dockerfile during release

[jtcohen6]

Currently, the dbt release flow:

• adds a requirements file to the dbt repo here
• uploads a new image to Docker Hub here

It does not:

• add a new dockerfile here

This gives the appearance of our not maintaining docker files / images for each version of dbt, when that's not true. We should either:

• add a dockerfile to the release commit
• if that's not possible, consider removing dockerfiles from the dbt repo, and instead redirecting community members to use the images

As possible, let's also backfill the missing dockerfiles for v0.17.0 through v0.19.0

Update: Per @kwigley's suggestion, we should just maintain the single simple Dockerfile in dbt, not tied to any one specific version. For clarity, we should remove the older versioned Dockerfiles.

We should continue to publish requirements.txt that are specific to each version.

@jtcohen6 thanks for the bookkeeping 😄

are those USER_ID and GROUP_ID supported for the old tags like 0.18.1 ?

Cleaned up docker resources in the dbt repo here dbt-labs/dbt-core#3019

Still need to update the dbt-release scripts to use dockerfile in the dbt repo for building and pushing a docker image for releases.

@edbizarro are you referring to the development docker image?
https://github.com/fishtown-analytics/dbt/blob/1f927a374c8bd52a12a20d892fed9d59cffd04f4/Dockerfile#L53-L57
If so, I believe the answer is yes.

The Dockerfile we use to publish dbt as a docker image to Docker Hub can be found here https://github.com/fishtown-analytics/dbt/pull/3019/files#diff-f34da55ca08f1a30591d8b0b3e885bcc678537b2a9a4aadea4f190806b374ddc.

Does this help with your question?
