go 1.5 is still *less* reliable than Go 1.2 on trusty. We see these
non-voting jobs fail more often in the final results. The jobs are
also retried 3 or 4 times where as the Go 1.2 jobs are 2 times.

We can make this more obvious by making the Go 1.5 jobs voting, and
not permit more retries that the other jobs. This will curse master.

Also, we made the wily unit tests voting by allowing more tries. Juju
and its test suite are less reliable on any Go other than 1.2

As Juju 1.25 is built with Go 1.5/1.6 on wily and xenial. We would
prefer to build it with Go 1.5 for trusty so that there are fewer
combinations to test and certify. But we wont accept Go 1.5 at this
time because stable Juju is even more unreliable than master.
Switching implicitly means accepting decline in reliability and
repeatability
