Bug 1518570 - Update task cluster configuration for oak. r=tomprince

The intent is to land this on central, to minimize the merge conflicts on oak

Oak is going to be used for Updater testing so needs release keys and such, and does not need android.
This approach is different than the previous oak approach in that it amends how we calculate 'trunk' and 'release'
projects to include 'oak', and then makes full nightlies produced on each push.
