Priority:	Minor

A first step on gathering information via telemetry related to Java 11.

In this ticket, we are going to gather the ClassNotFoundExeptions and some NoClassDefFoundError thrown in the master related to the Java packages moved to modules from Java 8.

Re: Telemetry gathering for missing classes due to Java modules

It has been tested in this scenarios:

A CNFE thrown by a `getClass().getClassLoader().loadClass` in a step implemented in a plugin
A CNFE thrown by a `Thread.currentThread().getContextClassLoader().loadClass` in a step implemented in a plugin
A CNFE thrown by a `getClass().getClassLoader().loadClass` in an action implemented in a plugin
A CNFE thrown by a `Thread.currentThread().getContextClassLoader().loadClass` in an action implemented in a plugin
A NoClassDefFoundError thrown by a call to a class moved to a module (`import sun.misc.BASE64Encoder;`) in a step implemented in a plugin
