This commit adds a new querystring parameter on the following APIs: - Index - Update - Bulk - Create Index - Rollover These APIs now support a `?prefer_v2_templates=true|false` flag. This flag changes the preference creation to use either V2 index templates or V1 templates. This flag defaults to `false` and will be changed to `true` for 8.0+ in subsequent work. Additionally, setting this flag internally sets the `index.prefer_v2_templates` index-level setting. This setting is used so that actions that automatically create a new index (things like rollover initiated by ILM) will inherit the preference from the original index. This setting is dynamic so that a transition from v1 to v2 templates can occur for long-running indices grouped by an alias performing periodic rollover. This also adds support for sending this parameter to the High Level Rest Client. Relates to elastic#53101
