[Proposal] Requiring Go 1.2 across the board

[John Meinel]

I believe the team lead meeting is last night, not tonight.
I'm fine with this, AFAIK the only specific change that needs to be made is
to get golang-go 1.2.* into ppa:juju/golang. I hope the people (Curtis and
Ian) are still planning on configuring the new Jenkins lander as a Precise
machine, since I still expect that to be the place where we are the most
likely to accidentally break things. (Most developers will be running
Trusty, so are likely to catch issues there.)
