Add a command to the satellite for cleaning up the Graceful Exit (a.k.a GE) transfer queue items of nodes that have exited. The commit adds to the GE satellite DB a couple of new methods, and its corresponding test, for performing the operations of the new command. Change-Id: I29a572a59689d63b24990ac13c52e76d65aaa917
