Migrate flush_unused_database from py-redis to sonic-swss-common #### Why I did it flush_unused_database using py-redis, but sonic-swss-common already support flushdb, so we need migrate to sonic-swss-common ##### Work item tracking - Microsoft ADO **(number only)**: 24292565 #### How I did it Migrate flush_unused_database from py-redis to sonic-swss-common #### How to verify it Pass all UT and E2E test #### Description for the changelog Migrate flush_unused_database from py-redis to sonic-swss-common
