[ML] Fix Nginx ML module manifest query to ignore frozen and cold tiers

[peteharverson]

What does this PR do?

The query defined in the json configuration files of anomaly detection modules are run to determine if the module is match for data in the selected index. These queries run over the full time range of the index so can potentially take a long time to return, particularly if searching over documents which are not in the hot or warm data tiers. This PR adds an extra condition to the query to ignore data from the cold and frozen tiers.
