Clickhouse-server can't restart succesfully until manual kill of clickhouse-odbc-bridge process

[fessmage]

Describe the bug or unexpected behaviour
Clickhouse-server can't restart succesfully until manual kill of clickhouse-odbc-bridge process.

How to reproduce
Run clickhouse-server with odbc dictionaries. Then try systemctl restart clickhouse-server - it will hang. Clickhouse-server process stopped, but clickhouse-odbc-bridge process stays running. Kill that process manually - and then restart of clickhouse-server continues succesfully.

Which ClickHouse server version to use
19.13.3.26

Expected behavior
Restart of clickhouse-server service must itself stop odbc-bridge, not requiring manually interaction.
