ClickHouse Querybuilder `.to_redacted_sql` enhancement

##Problem Statement

We want to log SQL queries being fired on Clickhouse but would also want to hide sensitive information from being logged.

Implementation Plan

1. Build to_redacted_sql method in ClickHouse::QueryBuilder class which generates redacted SQL

example:

where(column: 12) # .to_redacted_sql would generate: WHERE column = $1

One idea here is to keep track of binds and then only build SQL when to_sql is called and for to_sql_redacted we can pass redact: true
