There has been a case where the CI was broken on Friday and no one
noticied or fixed it and a RC build was built with broken tests.
The tests were disabled due to unknown test failures that have since
been fixed.
Also update the machine type used by GCB to be more powerful. This is
necessary for the tests to past because N1_HIGHCPU_8 is RAM constraint
and the tests crashes. I updated all jobs to use the new type which
hopefully will make the build faster as well.

* Work around Spinnaker issue wrt variables
Cloud Build variable reference need to stay from the ${var} pattern
to prevent Spinnaker from trying to resolve it. In all files that
are used by Spinnaker, we change variable reference to the $var form.
We made the minimum amount of change possible, and will review this
issue after the permanent solution is available.
