Feature Request: Support multi-stage docker builds

[lizardruss]

In my current project, we use a development build stage and a leaner production build stage to produce an image for local development and one to deploy.

I haven't found an option to specify a build target to use for for a multi-stage build. It would be great if this option could be added.

Thanks for the awesome tool!

Thanks for creating this issue! Yes we should definitely add that. We'll add the target option to the "images[].build" section in the .devspace/config file. Actually we also should improve the config for this section, because currently it is already possible to specify buildArgs, contextPath and dockerfilePath for building the image, but this functionality is not documented yet.

I will work on this today and we'll ship it with release 1.1.0, which should come out either today or tomorrow.

Feature is implemented in v1.1.0
