DeploymentConfig pre hook execPods do not have the same tolerations as the template

Issue

When creating a DeploymentConfig with tolerations defined, the pre-execPods or post-execPods do not have the same tolerations as the DeploymentConfig.

When this is run in an environment where taints/tolerations are heavily used to control workload, this is resulting in scheduling failures for the hook Pods and the DeploymentConfig is not rolled out.
