Submitted By: Pedro Salgado, psalgado@bnl.gov

Description: dCache pools will be upgraded to dCache 1.9.1-8:

• Pool: Fixed an issue with pools getting disabled on transfer errors. Pools now respect the replicateOnArrival flag (a regression from 1.9.0). Newly created replicas now have a last access time equal to the creation time rather than zero.
• Pool: Fixed HSM cleaner registration.
• Pools: Fixed LRU garbage collection (previous releases implemented least recently created, not least recently used).
• Pools + pin manager: Adds pin migration (previously mistakenly announced for 1.9.1-4, but was not present until 1.9.1-5).
