ct16k 7f8db4d8ed fix: add generation tracking to prevent keys surviving a clear operation
Running a Purge and a Get at the same time could allow an old key to be
pulled back into the cache if the request was initiated by a node that
had been cleared and sent to a node that hadn't. This patch tries to
mitigate this, by adding an additional `generation` field, that keeps
track of the number of purges issued. Requests are fulfilled successfully
only if boths ends of a request are on the same generation.
