Add ability to create custom compaction request

Details

      Enable coprocessors to submit custom compaction requests.

      This compaction request is used (if not null) through the entire compaction process. If no custom compaction request is submitted (its null - the normal case) then we we build a new compaction request via the usual mechanisms in the Store.

      Adding this mechanism is particularly useful when 'special' compactions are desired and you want to do things like: only change certain files for a particularly requested compaction or follow a single compaction through the queue.

    Description

      You can request that a compaction be started, but you can't be sure when that compaction request completes. This is a simple update to the CompactionRequest interface and the compact-split thread on the RS that doesn't actually impact the RS exposed interface.

      This is particularly useful for CPs so they can control starting/running a compaction.

      Update - Better description (3/20/13):
