Code review comment for lp:~cmars/juju-core/resolve-cs-series

Tests affected by the LTS change wrt uploading tools are now all passing
when the latest LTS series is "trusty". To run the tests as if trusty
were already released, run with:

go test -ldflags "-X
launchpad.net/juju-core/environs/config.latestLtsSeries trusty"

(This var is normally initialized when not set, from `distro-info
--lts`)

Added wallyworld. I could use a review from a tools distribution
perspective, as this is an area I am only superficially familiar with.
They were affected by the LTS series change so I've tried to make fixes
where test cases and setup had "precise" hardcoded, did not anticipate
having to upload tools other than a DefaultSeries, etc.

Thanks!
