For #20046, I found this while trying to get #20085 merged, as MySQL 8
tests were consistenly failing (5 times in a row) with this when
integration tests are run in parallel.
I used the `lhotari/action-upterm@v1` action to hook an SSH session into
the worker, and I noticed different errors in different runs, but all on
the same lines of this sample:
```
mysql> SELECT * FROM replication_applier_status_by_worker LIMIT 1 OFFSET 0\G
*************************** 1. row ***************************
CHANNEL_NAME:
WORKER_ID: 1
THREAD_ID: NULL
SERVICE_STATE: OFF
LAST_ERROR_NUMBER: 1146
LAST_ERROR_MESSAGE: Worker 1 failed executing transaction 'ANONYMOUS' at master log bin.000003, end_log_pos 25540153; Error 'Table 'server_datastore_mysql_TestTeams.host_mdm_apple_bootstrap_packages' doesn't exist' on query. Default database: 'server_datastore_mysql_TestTeams'. Query: 'TRUNCATE TABLE host_mdm_apple_bootstrap_packages'
LAST_ERROR_TIMEST
```
This uses
[REPLICATE_DO_DB](https://dev.mysql.com/doc/refman/5.7/en/change-replication-filter.html)
to configure the replica at runtime to replicate only the databases that
are configured with replicas and prevent any unexpected behavior.
