Implemented docker-compose testing env

[Frondor]

Be sure you have all dev dependencies installed first with npm i and docker-compose in your machine.
Then, execute ./docker-test script (an npm script could be used for it)

It uses docker-compose to bring a S3 service via localstack/localstack image mocking the real one (aws), and a simple test ftp server that may need some tweaks.
More services can be added as needed.

Update: https://hub.docker.com/r/scality/s3server/ looks good for s3 and spaces tests, gotta check it

Hey @Frondor! 👋

I got the test running on my system 👌
Currently working on the FTP driver to make it work better (as said in #55).

[Frondor]

That's cool! Please, let me know if you find something wrong, so it runs as smooth as possible.

If the FTP Driver gets fixed, we might be able to switch to a faster FTP server (the current image is quite slow, but works!).
I'm leaving another server commented in the docker-compose.yml file so we can try to implement it later.

Currently working on it for the next version.
