[openstack-dev] [Sahara] Instance customization for Bootstrapping the cluster nodes

Hello Everyone,

I am looking for a way to customize my Cluster nodes at cluster creation
time. This is something like: AWS EMR BootStrap Action:
http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/emr-plan-bootstrap.html

While creating an instance through nova boot command / UI, there is an
option to pass user-data through with cloud-init or cloud-config scripts,
that can customize the instance at creation time based on specific
environment or user need. Is there a similar way to pass cloud-init /
cloud-config scripts while creating cluster using Sahara?

Please Note: I do not prefer to bake these customization in the Sahara
image itself, I need to do these at the Cluster creation time, dynamically.

Thanks for the help.
