API for updating field formats

[stacey-gammon]

Background: https://discuss.elastic.co/t/set-kibana-field-format-using-apis-for-kibana-index/92352/2

We currently store field format information in a special format in the .kibana index. e.g.: "fieldFormatMap": """{"machine.ram":{"id":"percent"}}"""

For customers who wish to programmatically update field formatters, bypassing the UI, there is currently no officially supported way to do this, and the format may change at any time. If we introduced an API to update field formats this would be simpler.

Sounds inline with the new platform work anyhow, which will have all plugins communicating via an API.

Went to the _templates API expecting to see the current field formats so the same configuration could be applied to all environments. Is there a workaround for automated deployments?

If anyone has a work around on this, it would be greatly appreciated.
