IndexSettingsLifecycle requires a name to be set

Problem description

IndexSettingsLifecycle requires a name to be set which is not necessary if the API is used directly. According to the JavaDoc, this is the name of the policy to be used to manage the index. We use component templates to specify this setting.

The setting that I want to overwrite for the specific index template is the rollover alias. We could work around this issue by specifying it through otherSettings on IndexSettings.

It's actually worse since this cannot be worked around when reading the templates.

Hello, thanks for the report! This is an issue in the API specification used to produce the Java code, the policy name should be optional. It will be fixed soon and the Java client code will be updated to resolve this issue.
