We wrap both Driver and WebElement into VaadinDriverWrapper and VaadinELementWrapper.

Find-element methods of the wrappers call vaadinIsDone  - waiting until all client-sided async-calls are done.

Problem is - it happens that it is never done. E.g. that's the underlying probem of  MGNLTEST-198

Aim: Introduce Annotation to skip the vaadinIsDone-calls on class- and/or method-level.
