Juju-gui only show localhost as the deployment option

[fengxia]

Akshat,

Just to chip in some of my thoughts on this since we (disclosure, I'm a 
researcher at Lenovo) have had extensive discussions on a similar use 
case and consequently come down to the same challenge as you are 
currently looking at.

1. Juju CLI allows user to select controller, which essentially leads to 
a particular cloud/provider (these two are 1-1 mapping). Therefore, in 
practice it already supports multi-cloud scenario (last time I counted 
12 clouds out of box including local LXD and manual). The catch is, of 
course, the manual step of selecting the proper controller.

2. There are two schools of thought -- whether to have Juju being more 
intelligent so to handle multiple clouds `automatically` (for example, 
in bundle YAML specify which cloud a charm should be deployed to, which 
is one step further than OS series), or using Juju as-is and utilize 
something else as a wrapper to facilitate such mixed-cloud automation. 
The former option minimize tech stack so there is one set of technology 
to learn and manage; the latter gives flexibility, mitigate vendor lock 
in... I think the theme is not new, so it's really a matter of design 
preference

Juju team has done 90% of the heavy liftings. The former will require 
more in-depth of Juju knowledge, the latter requires less. I think the 
requirements, however, is clear, that there is a higher level of 
abstraction required above the current Juju existence so to drive this.
