Is your feature request related to a problem? Please describe
When using Index transforms, it's impossible to create an index transform with cardinality aggregation .
This feature is supported in ElasticSearch 7.10.2, so I'm not sure why it's not included in opensearch, which is derived from Elasticsearch 7.10.2.
Describe the solution you'd like
Include cardinality aggregation as one of the supported aggregations, when creating a new Index transforms.

Describe alternatives you've considered
There is no alternative I can think of other than using the search api, using the cardinality aggregation
