Merge lp:~nskaggs/juju-release-tools/add-snap-script into lp:juju-release-tools

[Nicholas Skaggs]

Add snap creation script for edge channel.

This script requests builds for https://launchpad.net/~jujuisquality/+snap/juju. It's installed on ci-master in the jenkins user crontab. It runs daily at 1700 UTC.

[Curtis Hovey (sinzui)]

I have some concerns inline.

review: Needs Information (code)

[Nicholas Skaggs (nskaggs)]

Replied with my own set of questions. In general if you want more time invested in cleaning this up, I'll do it. It's mostly just an edited clone of lp:ubuntu-core-snap; warts and all.
