* build openpilot docker container in jenkins

* use cache

* run all stages in parallel

* move device tests

* wrap in stages

* it's docker

* doesn't work, but jenkins should cache the image

* steps

* disable phone tests for now

* we're root

* enable everything

* clean up our mess

* skip checkout

* need a plugin for that

* remove that

* parallel

* Revert "parallel"

This reverts commit e3e5af9dc9db692d1b5552012d62393a5b8520dd.

* this is ugly

* Revert "this is ugly"
