Revert "Add support for binning of nested queries"

Color consolidation [WIP]

Download functionality on embedded dashboards (feature 3847)

 Allow positive numeric values for text fingerprint average lengths 

Previously this only allowed double values. If the average length
happened to be something like `13.0` some Javascript implementations
trim the `.0` and when the frontend POSTs the data, it includes `13`
instead. This was causing our schema validation to break as it was
looking for a `Double`.

This commit changes the schema to look for a positive numeric value,
not just a positive double which covers both cases.

Add support for binning of nested queries

This commit stores fingerprints and special type information for the
results of cards that have native queries, similar to what we store
for MBQL queries.
