Canvas does not use formatting from index pattern

[wylieconlon]

Kibana version: Master

Describe the bug:

This is a bug that affects both SQL and Docs data sources for canvas. I have chosen formatters for agent and bytes in my index pattern:

But in canvas, the format is always the raw value:

This is the same behavior with the SQL query SELECT agent, bytes FROM "kibana_sample_data_logs*"

Steps to reproduce:

1. Edit your index pattern to add a formatter to any field
2. Use that field in a SQL query or Docs query in canvas
3. The result is not formatted
