Install git in docker container to use pip packages from git+ssh

[bsedin]

Hello!

Thanks for awesome project! Had troubles building docker image because of package from git: https://github.com/stevenleeg/geemusic/blob/master/requirements.txt#L20

So I added git package to alpine. Also I added .git directory to .dockerignore and additional building step where build deps removed from container system.

Hmm, I don't really get what this is doing. It looks like you just moved the build depends to an environment variable and removed them after installing the dependencies?

The most important part is installing git, which fixes broken docker build because of: https://github.com/stevenleeg/geemusic/blob/master/requirements.txt#L20

Second - removing gcc, make, musl after we compiled all our libraries seems like a good practice.

Third - ignore .git files to speed up container building.

@kressh sorry about breaking the Docker build. I needed to use that fork originally because flask-ask broke the WSGI portion for Python3.6 because they switched StringIO to BytesIO, but AWS Lambda functions don't support byte-like request bodies unless you use ApiGateway, so I had to add in compatibility support between Python2.7 and Python3.6. I use ApiGateway now so this dependency isn't exactly necessary. I will clean up the requirements.txt file when I get home today, until then just keep using your working version if you don't mind.

@stevenleeg this is why I want tests!

@kressh wanna try it out? I fixed the dependency issue in #231.

Fixed in #231.
