Lock yarn dependency, fix chrome dependency, upgrade node
This creates a new image which:
- upgrades node from v7.x to v8.x
- upgrades yarn to v1.0.2 and locks it at that version
- upgrades chrome to v61 (fixing broken master)
It also works around broken Chrome version images by commenting out build images which can no longer be built due to yanked PPA versions. Adds documentation for working with older versions of Chrome when images need to be recompiled.
