Even though we generate documentation automatically in CI, the source tree still contains checked in, generated endpoint documentation in docs/endpoints.
We should remove these source files from the tree. We need to make sure to
- not break automatic website generation with support/mesos-website/build.sh,
- not break the local website generation workflow with site/mesos-website-dev.sh, and
- not break local website generation workflow with rake via site/Rakefile.
