Comment 10 for bug 1907250

I'm seeing this error:

2022-05-03 22:04:39 io INFO [7f91c2e53e00] starting 8 io-threads, using backend 'linux_epoll'
2022-05-03 22:04:39 main ERROR [7f91c2e53e00] Error: option 'DEFAULT.name' is not supported

The error can be reproduced using this bundle http://paste.ubuntu.com/p/mdY9dJhktH/ + the patch recently merged at https://review.opendev.org/c/openstack/charm-mysql-router/+/834359 (probably at this point in time the change should be available in the latest/edge channel).

When I try to generate the bootstrap files that the mysqlrouter creates we can find that the `name` key is added by it and it's not added by the charm, see below:

# Bootstrapping MySQL Router instance at '/var/lib/mysql/keystone-mysql-router'...

- Creating account(s) (only those that are needed, if any)
- Verifying account (using it to run SQL queries that would be run by Router)
- Storing account in keyring
- Adjusting permissions of generated files
- Creating configuration /var/lib/mysql/keystone-mysql-router/mysqlrouter.conf

# MySQL Router 'keystone-mysql-router' configured for the InnoDB Cluster 'jujuCluster'

After this MySQL Router has been started with the generated configuration

    $ /usr/bin/mysqlrouter -c /var/lib/mysql/keystone-mysql-router/mysqlrouter.conf

InnoDB Cluster 'jujuCluster' can be reached by connecting to:
