When there is no compaction work Compactors will wait progressively longer (between COMPACTOR_MIN_JOB_WAIT_TIME and COMPACTOR_MAX_JOB_WAIT_TIME) before checking in with the Coordinator for work. The wait time is used to reduce the number of RPC calls to the Coordinator. However, with large max wait times Compactors may sit idle when there is work to do. This change allows the user to configure the Coordinator to wake waiting Compactors when there is work in the queue. Closes apache#4664
