* run tests with ./node
* remove addons from test-ci suite, because it creates a dependency loop
  nodejs -> node-gyp -> nodejs which is painful to manage.
* disabled because it requires stdin:
  + test-stdout-close-unref
  + test-regress-GH-746
* test-tick-processor fails on ppc64 and s390x, currently investigated
  https://github.com/nodejs/node/issues/2471
* test-cluster-disconnect sometimes fails on busy buildd, forwarded upstream
  https://github.com/nodejs/node/issues/3383
* test-fs-watch is flaky, might be related to https://github.com/nodejs/node/issues/4082
* huge timeout value for all platforms, buildd could be busy
* test-npm-install and test-release-npm must fail, debian package dfsg-repacked npm out
* ability to override CI_NATIVE_SUITES, CI_JS_SUITES
* disable tests failing because DNS is disabled
* sequential/test-http2-session-timeout is flaky https://github.com/nodejs/node/issues/20628
