REST API configuration changes

The following items have been added to the REST API configuration. They will not need to be manually updated, the router will add the new keys with default values. Note that this is not a complete list of all changes, it only contains the changes that will be automatically added when upgrading the router.

If the router is configured via confd and confcli, these changes will be applied by them. This section is only relevant if the router is configured via the v2/configuration API.

• Added the session_translation_function key.
• Added the tuning.selection_input_item_limit key.
