    Only validate credentials on create based on resources

    This change relaxes the validation which checked for credentials
    on stack create and update.

    As implemented, having any of the following resources
    in the template will result in credentials being mandatory
    on create and update:
    * AWS::AutoScaling::ScalingPolicy
    * OS::Heat::HARestarter
    * AWS::CloudFormation::WaitConditionHandle

    For all other templates, credentials are not needed.

    When trusts are merged, this logic could also be used to decide
    whether a trust token needs to be created at all.

    Fixes bug: #1217617
