Download a folder from repository

What does this MR do?

This is based from the Community contribution MR from @kiameisomabes: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20604.

Add links to download a folder from repository in different formats (zip, tar.gz, tar.bz2, or tar).

Add GetArchiveRequest to git-archive params.

Modifies Git::Repository#archive_metadata to append path to ArchivePrefix so it'll not hit the cache of repository archive when it already exists.
