ChangeExecListener-API cannot be used due to HubChangeExecListener

[ckulenkampff]

Environment

Liquibase Version: 4.2.2

Liquibase Integration & Version: Java 1.8

Description

The API for providing a custom ChangeExecListener is broken, because the internal HubChangeExecListener is now obligatory.

Steps To Reproduce

• Implement a custom ChangeExecListener
• Provide it to Liquibase through Liquibase.setChangeExecListener(ChangeExecListener)
• Perform an update like Liquibase.update(String) that directly accesses the database

Actual Behavior

A RuntimeException ChangeExecListener already defined is thrown.

Expected/Desired Behavior

The provided ChangeExecListener is used without an exception. Being able to add multiple ChangeExecListener would be optimal.

Additional Context

Currently I use the ChangeExecListener for adding database specific setup commands when the first changeset is actually executed.
