[Field formatters] Additional variables for URL field formatter

[gimmic]

It might be nice for UI-driven integration/pivots if more aspects of the current context around a document could be made available as variables in the index field label templates.
Currently supported: {{value}}

Passing this as a URI variable in the URL field template can build out some interesting pivots to other tools or human-driven interactions as pivots. I am currently using this to pass the document _id to a third party tool on human click.
Example of the field label as a URL template in a pivot: http://10.20.20.50:8080/search/?docid={{value}}

Other values that might be nice to be able to provide additional context could include:
{{ index }} the current index pattern (can be set statically already since field templates are tied to index patterns)
{{ timerange }} the current date range
{{ user }} the authenticated kibana username
{{ now }} a current datestamp
{{ field-fieldname }} other specific fields in that document

@gimmic Based on context, it looks like you are asking about the URL field formatter.

@wylieconlon Yes, thank you for clarification, I wasn't sure what to label it as.

Having this feature would greatly enhance the capability to pivot from discover to dashboards. It would be a significant workflow benefit to enterprise users who need to pivot often and quickly.

Closing this because it's not planned to be resolved in the foreseeable future. It will be tracked in our Icebox and will be re-opened if our priorities change. Feel free to re-open if you think it should be melted sooner.
