Requirement

use clickhouse-go instead of ch-go in write path.

Problem

The ch-go library does not support multi-instance writing. This could lead to performance bottlenecks. We have chosen to use clickhouse-go only.

Proposal

1. introduce new dbmodel consist of new data type (e.g. using []byte instead of string on trace id, span id ...).
2. ToDBModel and FromDBModel use the new dbmodel.
3. deprecated exist ddmodel.
