Mesos Websitebot is flaky

Mesos Websitebot Jenkins job is sometimes failing during the endpoint documentation generation face. It looks like it is timing out on getting a response from the /health endpoint of the master.

Example failing build: https://builds.apache.org/view/M-R/view/Mesos/job/Mesos-Websitebot/1899/
