Only up to 100 index patterns are shown in dropdown for available index patterns

[ppf2]

A user reported that when they click on the dropdown for index patterns in the "Add Layer" editor of Maps, their index pattern is not showing up (until they perform a search for it).

Checking the response of the underlying query issued by Kibana:

https://<your_kibana_endpoint>/api/saved_objects/_find?fields=title&fields=fields&per_page=100&search=*&search_fields=title&type=index-pattern

I am pretty sure that this is because we only return the first page of 100 index patterns found in saved objects to the drop down. In this case, there are close to 700 index patterns:

  "page": 1,
  "per_page": 100,
  "total": 699,

I suspect that this might(?) be the expected behavior for performance reasons. If we do not intend to page through and return all index patterns to the drop down, it will be helpful to add a tooltip to let the end users know that we will only return up to 100 index patterns in the dropdown (i.e., refine the search as needed).
