Description

Problem:
Configuration types posted in the blueprint or in the cluster creation template need to be validated before the cluster provisioning is started and cluster resources are persisted in the database.

This validation should be done when the topology configuration comes together so that it's not modified and enhanced further.

Currently the topology configuration is modified after the validation thus on blueprint deployments the cluster provisioning may fail despite of the right configuration.
