[Enhance]: Ensure Consistency of Database and Parameters in Newly Created ClickHouse JDBC Connections

[itinycheng]

What happened?

Description

• Currently, the URL configuration is used directly as the URL for the ClickHouseDriver.
• The current format of the ClickHouse JDBC URL is as follows: jdbc:(ch|clickhouse)[:<protocol>]://endpoint1[,endpoint2,...][/<database>][?param1=value1&param2=value2][#tag1,tag2,...].
• When we use the local mode to query a distributed table, a URL address is created for each shard to connect to the local table.

Issue

We need to ensure that the newly created connections contain the same database and parameters as the input URL. This means we need to append [/<database>][?param1=value1&param2=value2][#tag1,tag2,...] to the new URL.

Proposed Solution

We propose to modify the URL creation logic to ensure that the database and parameters from the original URL are included in the URLs for each shard. This will ensure consistency across all connections.

Impact

This change will improve the consistency of our connections and prevent potential issues caused by discrepancies in the database or parameters used in different connections.
