create hll column with hll config for fast hll calculation

[jshencode]

Is your feature request related to a problem? Please describe.
Currently we support fast hyperloglog calculation based on pre computed hll column which requires users to create and ingest.

Describe the solution you'd like

1. Schema: when user create a column and specify hyperloglog in the column config, we should automatically create the hyperloglog column
2. Ingestion: ingestion into the hyperloglog enabled column should automatically create hll value and ingest into the hll column
