[FLINK-3418] Don't run RocksDB copy utils in external process
This was causing to many problems with security tokens and yarn. Now,
let the RocksDB backup run in a thread but
don't interrupt these Threads anymore on closing. The Threads will close
themselves because the copy operation will fail because of a
FileNotFoundException when the state directories are being cleaned up.
This also removes the ExternalProcessRunner because it is not needed
anymore and using it causes too many headaches.
