Fixed GCE playbooks so that they're more like the AWS playbooks.

[twiest]

Namely the GCE playbooks now:

• Create infra nodes
• Correctly label nodes in OpenShift
• Setup masters as nodes as well (needed for sdn)
• Removed set_infra_launch_facts_tasks.yml as it's not used anymore.

@menren @sdodson Hey Guys, mind looking at this please?

It should only affect GCE, and I tested it using the online deployment type against GCE and everything is working well for me.

@menren This is the code that enables infra nodes that I talked about in PR #658. Please make sure this doesn't break you. This is meant to make the GCE code work more like the AWS code.

Remove the debug?

As I mentionned, we need to do some check in the case we deploy without infra-node.

It seems good to me with infra-node :

PLAY RECAP ******************************************************************** 
github-master-8fc35        : ok=173  changed=56   unreachable=0    failed=0   
github-node-compute-91dfe  : ok=61   changed=24   unreachable=0    failed=0   
github-node-compute-bb1fb  : ok=61   changed=24   unreachable=0    failed=0   
github-node-infra-25513    : ok=61   changed=24   unreachable=0    failed=0   
localhost                  : ok=49   changed=6    unreachable=0    failed=0

@menren @sdodson Please review again, I've addressed all comments.

@menren please also make sure it doesn't break you.

I also tested with and without infra nodes.

With infra nodes:

PLAY RECAP ******************************************************************** 
localhost                  : ok=43   changed=6    unreachable=0    failed=0   
twiesttest2-master-ff011   : ok=166  changed=56   unreachable=0    failed=0   
twiesttest2-node-compute-34b42 : ok=61   changed=24   unreachable=0    failed=0   
twiesttest2-node-infra-9cbf6 : ok=61   changed=24   unreachable=0    failed=0   

Without infra nodes:

PLAY RECAP ******************************************************************** 
localhost                  : ok=37   changed=4    unreachable=0    failed=0   
twiesttest3-master-ac34a   : ok=166  changed=56   unreachable=0    failed=0   
twiesttest3-node-compute-ba3c1 : ok=61   changed=24   unreachable=0    failed=0

Good for me !
