We are planning to upgrade build.webkit.org to latest Buildbot. Newer Buildbot (by default) prints all the environment variables of master for any MasterShellCommand command (since https://github.com/buildbot/buildbot/pull/2408). As a side note, we also tried to change the default behavior in https://github.com/buildbot/buildbot/pull/4772, but the PR wasn't accepted. We should update the MasterShellCommand steps to ensure that we set logEnviron to False.
