[Meta] Support data streams in Kibana

[stacey-gammon]

What are data streams

elastic/elasticsearch#53100

What does Kibana need to do to support them?

• Create index pattern data object from data stream
  • User can create wildcard based on data stream. This will query a new ES endpoint. Data stream selection in index pattern management #65601
  • Work with design and agree upon modifications to existing flow (in progress) Index Pattern Data stream support - ui design #67959
  • Field list can be generated from data stream wildcard (should not require changes)

Discuss issue regarding ES api - #64858
_resolve endpoint - elastic/elasticsearch#57626

Just wanted to mention that @martijnvg lead a discussion with some kibana and es-ui engineers and the main two takeaways are:

Verify kibana apps won't be broken by inability to get individual docs from a data stream. Note - if your app works with index aliases it will work with data streams.

While it isn't necessary to have a UI specifically for creating index patterns from a data stream it would be beneficial. There will likely be a one-to-one relationship to index patterns and data streams. We discussed whether we should hide data stream related indices from the index list but felt it would likely confuse users. We could potentially display a data stream tag next to data stream related indices.
