Juju as a snap

[Nicholas Skaggs]

The Juju client has been snappified and pushed to the juju store. Note 
for now it's just an amd64 build.

snap install juju --beta --devmode

The beta channel contains the latest beta, 2.0-beta13. This is a sneak 
preview of further builds, including the latest crack available in the 
edge channel as development happens.

Note, that you will need to use juju add-credential to re-add your 
credentials for the snap -- credentials are not shared with the debian 
package. Also, should you have the debian package (from the archive or 
ppa) installed, it has priority in PATH for 'juju'. Uninstall the 
package, or run the snap directly by calling /snap/bin/juju.

Feedback is welcome and appreciated! If you are running ubuntu 16.04 you 
already have snappy installed. Give it a try!
