Removed the release check from the pre-deploy task.

The pre-deploy task generates the containers-prepare-parameters.yaml
file according to the selected release to deploy.
Since the create-script in the undercloud section always
create the containers-prepare-parameter.yaml file, the check
on the overcloud-deploy role is not necessary anymore.
