Add support for shared volume across nodes in cluster

[cjh1]

I think ec2_pod supports this?

What do you mean by shared volume? I was under the impression volume's can only be attached to a single instance at a time - or do you mean the process of detaching and attaching to a new instance?

I mean sharing via NFS or similar ...

But yes we need to look at support attaching detaching as well.

ec2-pod role does not support this out of the box, I do however, have some ansible scripts kicking around that does this. Let me see if i can put hands on it

Not sure if this is helpful or not, but fwiw: https://github.com/OpenGeoscience/nex/blob/master/experimental/celery_performance/setup.yml#L41-L129

The current gridengine playbook shared the root filesystem via NFS.

We also need to be able to configure the root volume size when we create a cluster ( head and data node independently )
