Use date field formatter for date_histogram axis

[nkaranth]

I am trying to create Date Histogram whose default time format is coming as : YYYY-MM-DD as format selected is default. For time field i am trying to change the Date format to something else like MMM Do YYYY or anything else. It gets changed in field but dashboard is not getting updated with required changed format.

The date histogram axis ticks do not use this field formatter as it would lead to some pretty nasty labels most of the time. We should probably check if the field uses a non-default field formatter and use it in that case.

This is definitely closed, as visualizations now respect the setting dateFormat:scaled for custom date formats.
