Kibana Control Visualization : allow size for dynamic options

[jguay]

Describe the feature:
Ability to set term aggregation size when using "Dynamic Options" in Input Control Visualization
Describe a specific use case for the feature:
At the moment (in 7.6.0) the size parameter for the term aggregation is only available when Dynamic Options is disabled :

When using "Dynamic Options", there is no size field so the visualization runs a term aggregation with default size (10) which looks like this:

{"timeout":"1000ms","terminate_after":100000,"size":0,"aggs":{"termsAgg":{"terms":{"order":{"_count":"desc"},"field":"shard.index"}}},"stored_fields":["*"],"script_fields":{},"docvalue_fields":[{"field":"enrich_executing_policy_stats.task.start_time_in_millis","format":"date_time"},{"field":"job_stats.data_counts.earliest_record_timestamp","format":"date_time"},{"field":"job_stats.data_counts.latest_record_timestamp","format":"date_time"},{"field":"source_node.timestamp","format":"date_time"},{"field":"timestamp","format":"date_time"}],"_source":{"excludes":[]},"query":{"bool":{"must":[],"filter":[],"should":[],"must_not":[]}}}

@jguay is this request mainly because of performance issues? or is there another reason?

Closing - with the ability to load more suggestions added to the new options list, and since there was no clarification on whether this is a performance request, I think that this should be covered 👍
