Extract EE specific files/lines for .

We have the following files containing EE specific code. We should move them to ee/

Note: Updated 2019-08-27.

• .gitattributes
  • This is due to the VERSION=ours line, which can be removed after the merge.
• .gitlab-ci.yml
• .gitlab/ci/rails.gitlab-ci.yml
• .gitlab/ci/test-metadata.gitlab-ci.yml
• .gitlab/issue_templates/Feature proposal.md
• .license_encryption_key.pub
  • Should we just always include this? It's fine for it to be unused.
• .rubocop.yml => https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/32287 / https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/15693
• CHANGELOG-EE.md
• CHANGELOG.md
  • We should always be using the CE version, but it's unclear why they differ to begin with. Possibly due to https://gitlab.com/gitlab-org/release-tools/issues/169.
• CONTRIBUTING.md
  • Might be legal ramifications here?
• Gemfile => https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/16080
• Gemfile.lock => https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/16080
• PHILOSOPHY.md => https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/32287 / https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/15693
• README.md => https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/32287 / https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/15693
• crowdin.yml
  • Doesn't need to exist in CE, it can just exist in the final merged codebase.
