Merge lp:~elopio/snappy/test_go_version into lp:~snappy-dev/snappy/snappy-moved-to-github

[Leo Arias]

Translated the version integration test to go.

This one is a little tricky. We can't pass the version from the host to the testbed, because we accept relative versions like -1 or nothing to mean latest. So we would have to query the system-image server for the latest image, and calculate the relative version. But then we would need to know the device, which can be a lot of things and we don't take as an argument. Much too work for not much value IMO, so I settled for checking the value from the config.

Looks good, +1

Maybe a system-image client as you mention can become useful, we can get all the required data from snappy info, then it's just a matter of parsing a remote json.
