Style of Heat template outputs are not consistent

[hongbin]

We'd better to make the outputs of heat template consistent. In particular, each template should have these five output keys:

* api_address
* XXX_master(s)
* XXX_master(s)_external
* kube_minions
* kube_minions_external

Fix proposed to branch: master

[Guangya Liu (Jay Lau) (jay-lau-513)]

Why did each template need the following two?
* kube_minions
* kube_minions_external

Those should belong to kubernetes only, comments?
