Node instances are now created on deployment creation (eagerly); storage-manager's update_node method is now strictly for update (no upsert); fixed state_version values in resources.py; created the test_storage integration test
CLOUDIFY-2587 storage-manager put_node method now returns the initial state_version - refactored it out of resources.py as it seems like an implementation detail that should be left for the storage impl
CLOUDIFY-2587 temporarily modified .travis.yml for tests sake
CLOUDIFY-2587 corrected put-node API response status code to 201 and not 200; fixed error message for bad input of node patch call; reverted .travis.yml
CLOUDIFY-2587 modified ES-storage-manager's update method, removed unnecessary get call before update
