Add an integration (blend) in a customer account, based on a template. This will create an instance (blend) of the template in the account, and activate the schedule from the template (if any).
template_prevent_duplicates (optional): if set to true, no duplicate instance will be created for the same template, instead the same instance will be updated. Note that the input parameters (inputs) are taken into account to determine duplicates. An instance with other input parameters will not be considered a duplicate. This allows installing e.g. an instance where project=A and a second instance where project=B.
