changes in tests to work in docker-dev-env

[juanrmn]

It works along with some changes in this PR to docker-dev-env:

• docker-compose/docker-compose.yml -> windshaft service section, mounts lib and test volumes from local folder.
• docker-compose/mounts/windshaft_test.js -> tests config, also mounted in main docker-compose.yml file.
• (docker-compose/CartoDB-SQL-API_lib_server.js.patch) -> For Cartoframes, redirect Maps-API requests.

Yeah, nice work @juanrmn. it makes sense.

Even I'd go further and I'd require both Redis and Postgres up and running in their respective ports.

Thanks for sharing it.
