Add support to Azure k8s cluster

[katcipis]

There is a new cli made in python that can create k8s cluster integrated on Azure Container Services:

It seems really cool, although requires a new cli and it is a reasonably new feature. Perhaps it is a good idea to stay with the classic CoreOS (Linux Container ? :P) approach for now and use this later when we got things stable.

I don't see a problem in starting implementation of support for this service and I don't think it conflicts with giving the option of maintaining classic approaches. IMO klb would be much more complete when it supports all kinds of services from the main providers. So, as long as we keep things modularized, clean and organized, I say "the more the merrier" :)

@vitorarins actually I was just making a point for not implementing this right away, it will stay on the backlog for now :-). The amount of time is finite ;-)

[vitorarins]

@katcipis I think accidentally we mixed two things here, which is the support for the new cli and the support for Azure Container Services. So I will open another issue for the new cli support.

[katcipis]

@vitorarins makes sense to have two issues, but they are related, this issue will depend on #85, and solving #85 will depend on building a strategy on how we will migrate/coexist both cli's (or not if we make an atomic upgrade).

You can create another branch (using CLI 2.0) and start your tests...
...something like KLB 2 ?

[katcipis]

@fabio-hara definitely 👍

We now have support to using both azure cli 1.0 and 2.0
