Build simple script to make running scenarios easier

[leifmadsen]

Right now, when you go and run kube-centos-ansible (more on that later), it starts to get a little wordy. For example:

ansible-playbook -i inventory/virthost/ virthost-setup.yml

It would be a lot nicer to do something like...

kean setup

kean would be shorthand for kube-ansible which is the new proposed name for this project, since we're not strictly limited to centos any more.

Scope of kean

So basically I just want to build a simple (lolz...) bash script which mostly just wraps some commands with simplified versions. The initial version should support the following:

• setup: virthost-setup.yml
• deploy: kube-install.yml
• teardown: vm-teardown.yml
• build: builder.yml

Some environment variables could be loaded from ~/.kean.cfg which would contain things like the inventory path to use. We could start expanding on things like adding other Ansible variables that would be passed in like -e etc. I don't think that should be strictly necessary for the initial deploy.

Other Thoughts

The purpose is to make iterating a bit easier and to make the barrier of entry a bit lower for people coming to this repository. We don't necessarily want to replace everything and make something incredibly complicated, but rather just build out some shorthand from the larger commands we have now.

Relates to #122 (comment)

Also talked to @dougbtv some more about this. It would be great if you used a syntax like:

kean <action> [inventory]

Where [inventory] was optional, with a default of vms.local.generated. An example would be something like kean setup virthost where virthost would reference ./inventory/virthost/.

If vms.local.generated is not found, then provide some helpful output telling you what is happening.
