What this PR does / why we need it:

Currently, we use the klog in the cert-generator and the controller-runtime logger in other controllers, such as the experiment-controller. So the manager output logs using a different format from the other controllers for the cert-generator, as shown below:

...
{"level":"info","ts":"2023-08-18T04:36:53Z","msg":"Starting server","kind":"health probe","addr":"[::]:18080"}
{"level":"info","ts":"2023-08-18T04:36:53Z","msg":"starting server","path":"/metrics","kind":"metrics","addr":"[::]:8080"}
I0818 04:36:54.087010       1 generator.go:199] Generating self-signed public certificate and private key.
{"level":"info","ts":"2023-08-18T04:36:54Z","logger":"controller-runtime.healthz","msg":"healthz check failed","statuses":[{}]}
I0818 04:36:54.334683       1 generator.go:255] Trying to patch ValidatingWebhookConfiguration adding the caBundle.
I0818 04:36:54.441560       1 generator.go:282] Trying to patch MutatingWebhookConfiguration adding the caBundle.
...

However, we should use the same format to improve the visibility of the logs in the manager.
So I replaced the cert-generator logger with the same as the other controllers one:

var (
log = logf.Log.WithName(ControllerName)
)

After applying this patch, the manager will output logs in the following:

...
{"level":"info","ts":"2023-08-18T04:38:16Z","msg":"Starting server","kind":"health probe","addr":"[::]:18080"}
{"level":"info","ts":"2023-08-18T04:38:16Z","msg":"starting server","path":"/metrics","kind":"metrics","addr":"[::]:8080"}
{"level":"info","ts":"2023-08-18T04:38:16Z","logger":"controller-runtime.healthz","msg":"healthz check failed","statuses":[{}]}
{"level":"info","ts":"2023-08-18T04:38:16Z","logger":"cert-generator","msg":"Waiting for certs to get ready."}
{"level":"info","ts":"2023-08-18T04:38:16Z","logger":"cert-generator","msg":"Succeeded to be mounted certs inside the container."}
...
