Best practices for index USING HASH (...or USING HASH WITH BUCKET_COUNT) ?

This is about CRDB's hash sharded index feature for sequential indexes / primary keys: https://www.cockroachlabs.com/blog/hash-sharded-indexes-unlock-linear-scaling-for-sequential-workloads/

Is there any way to use this feature?

I've tried passing various arguments to `_create_index_sql()`:

`condition=`
`include=`
`db_tablespace=`
`expressions=`

With no success.

It may require an extra entry in https://github.com/cockroachdb/django-cockroachdb/blob/master/django_cockroachdb/schema.py to handle this use case?

Any comments, thoughts, appreciated.
