Index templates created in the 5x line can still be present in the cluster state
through multiple upgrades, and may have more than one mapping defined. 8x
will stop supporting templates with multiple mappings, and we should emit
deprecation warnings in 7x clusters to give users a chance to update their
templates before upgrading.
