SLING-4318 servlet that lists versions, potential conflict with V selector

[Bertrand Delacretaz]

Hi,

For SLING-4318 Tomek's contribution uses the V selector that I
suggested so that foo.V.json lists the versions of the foo node.

Putting this servlet in our servlets.get bundle might interfere with
existing user servlets that use this selector.

How should we avoid this potential collision? Put the new servlet in a
different bundle? Make its selector configurable?
