Document/Add example of how to use TestBench in MPR projects

[mstahv]

If a user has MPR in use, it is impossible to write test cases that interacts with parts that use both V7/8 and V14+ code.

Because TestBench Elements are specific for a Vaadin version is not possible to have both TBElements for the same components at the same time.
It should be possible to use TBElement API from one of the versions and WebElement API for the other version.
An example on how those can be used together would be help understand limitation and possibilities regarding how to use TestBench in an MPR project.

This is critical for our customers. For them this feature doesn't exist if it is not documented or we have an example of it. Many customers can't upgrade if they can't test their application.

Vote for this. We're about to start our V7 -> V14 migration and being able to keep our automation tests running as we do this in a phased manner with MPR is key to a successful and risk free migration.

Is there any update?
