Support `require_client_cert` in Docker image

The Dolt SQL server Docker image won't currently work with the new `require_client_cert` configuration setting. This is because the Docker image initialization code launches a Dolt SQL server and then uses `dolt sql` to access that server to add or configure users. This is an issue with the new `require_client_cert` feature, because when `dolt sql` connects to that running Dolt SQL server, it doesn't have a client certificate to use.

To fix this, it seems like we need to change the initialization logic in the Docker image so that we no longer rely on running `dolt sql` when the SQL server is running, such as running any `dolt sql` commands before starting the SQL server, or stopping the SQL server and restarting it after running the `dolt sql` commands if we detect the `require_client_certs` mode is enabled.
