Added setting, that defines, at which point should be .git removed.

Last year I had mentioned, that in some cases it could be required to have .git folder during build (e.g. enhancing application version). For this specific reason I've added new configuration named git_folder_handling. This config could be set to three options:

• DELETE_BEFORE_BUILD - the default option, that removes .git folder before build starts. This is original behaviour.
• DELETE_AFTER_BUILD - this option covers mentioned state, when .git folder is available during build, but is removed before zipped artifact is created.
• DISABLE_DELETE - the option, that leaves .git folder at project during build and also is zipped to artifact.

That would be quite an overkill, those values are Enum, so standard usage is with enum name. The default value is GitFolderHandling.DELETE_BEFORE_BUILD. Maybe the enum could have better name.

LGTM, but could you move the enum definition into a module other than flux_config? (Because it is intended to only supply configuration values, not any types that are part of the config's logic)

That's a good point. I'll create common enum module later today, as soon as I get to my computer.
