      Description

      The recently added Wait and Notify processors allow a flow file to be held at the Wait processor until a signal is received in the Notify processor. It would be nice to be able to wait for N signals before releasing.

      One way this could be done is to have a property like "Signal Count" on the Wait processor, and then count the keys in the cache starting with some pattern, and release when the # of keys equals the signal count.

      This would require the ability to get all the keys from the cache, or at least get all keys matching a pattern:
