ConfigurationPersistenceManager.exists does not handle factory configs (so config admin interfaces with factory = true). This prevents from using ConfigurationUpgradeStepFactory for upgrading factory configs.

Steps to reproduce

1. Start 7.0.x or 7.1.x
2. Create a new instance for an arbitrary factory config, for example AnonymousUserConfiguration, OpenIdConnectProviderConfiguration, DestinationWorkerConfiguration etc.
   This creates a config instance like com.xxx.OpenIdConnectProviderConfiguration-bab76645-06b9-44d0-8a5d-7b49802b1d43.config
3. Stop portal
4. Write a new upgrade step for the affected module like this on 7.1.x or master:

   package com.your.package;
   
   import com.liferay.portal.configuration.persistence.upgrade.ConfigurationUpgradeStepFactory;
   import com.liferay.portal.upgrade.registry.UpgradeStepRegistrator;
   
   import org.osgi.service.component.annotations.Component;
   import org.osgi.service.component.annotations.Reference;
   
   @Component(immediate = true, service = UpgradeStepRegistrator.class)
   public class TestUpgrade implements UpgradeStepRegistrator {
   
   	@Override
   	public void register(Registry registry) {
   		registry.register(
   			"a.b.c", "x.y.z",
   			_configurationUpgradeStepFactory.createUpgradeStep(
   				"com.old.factory.config.ClassName",
   				"com.new.factory.config.ClassName"));
   	}
   
   	@Reference
   	private ConfigurationUpgradeStepFactory _configurationUpgradeStepFactory;
   
   }
   

5. Build and deploy the updated module
6. Run the upgrade tool: java -jar LIFERAY_HOME/tools/portal-tools-db-upgrade-client/com.liferay.portal.tools.db.upgrade.client.jar
7. Wait until it finishes the upgrade

Expected Result: The Configuration_ table contains the renamed factory and instance.
Actual Result: The record in the Configuration_ table is untouched, no renamed configs created

It's the same if you are using a .cfg or .config file.
