Support IAE

I'll start prototyping here: https://github.com/snowch/IBM_Analytics_Engine_Examples and move to a new IBM-Bluemix repo. I've decided to create a new repo rather than branch the old repo because there will be a transition period during which both products will be available.

1. Create a cluster through CLI
2. Configure an object store to use with the cluster (using the customization script during startup)
3. Query data residing in object store using Spark
4. Spin up a cluster with Hadoop pack, configure an external Hive metastore (in Compose MySQL), create a Hive table on data that resides on object store
5. Modify the object store setting to point to a diff object store instance (using the customization script as an adhoc operation)

@cyborg7 can you point me to the documentation listing the steps I need to perform for item 5?
