@edwardfward Can you please comment on the state of this PR?

Please add this test case to the certification test.

https://github.com/dapr/components-contrib/blob/main/tests/certification/state/mysql/mysql_test.go

You can see some other components which use a dedicated component yaml for a test case - please don't edit the existing component yaml used in tests.

We will want to dynamically generate a certificate - then start a MySQL server via Docker configured to use this certificate, then have the component yaml specify the required certificate.

You may need to do so by using the secret store reference to load the contents from file or an environment variable.

Please do not hardcode a certificate in the component yaml and do not check in a certificate file.
