Major Description
When partition assignment happens we first try and add the active tasks and then add the standby tasks. The problem with this is that a new active task might already be an existing suspended standby task. if this is the case then when the active task initialises it will throw an exception from RocksDB:
Caused by: org.rocksdb.RocksDBException: IO error: lock /tmp/kafka-streams-7071/kafka-music-charts/1_1/rocksdb/all-songs/LOCK: No locks available
We need to make sure we have removed an closed any no-longer assigned Suspended tasks before creating new tasks.
