Strange error during scaling.

I am not 100% sure about this one, but the following changes seem to have made scaling more reliable.

Before when scaling down to one instance and the scaling up to for instance three instances Elastic Search would not start on the new instances.

Starting javamanager and elasticmanager in the same task seems to prevent elastic search from starting during scale operations.

Splitted these calls into separate tasks.

Modified the Elastic Search Data path. And put the logging on the file share for easier access.

Added gracefully shutdown to worker role.
