StoRM TAPE REST implementation

• should be already available according Stephan

CMS status

• ~ 3 sites ready to be switched to TAPE REST
• davs protocol in Rucio already configured for TAPE RSEs
  • Rucio automatically sends transfers requests from TAPE RSEs with "bringonline timeout"
  • this is sufficient for FTS to use TAPE REST for davs transfers
• now it is sufficient just to delete SRM protocol

ATLAS status

• details tracked in the Tape REST twiki timeline (FZK, CERN in production)
• stuck while trying to understand if it would make sense to reorganize storage namespace for tokens
  • no reorganization
• revive effort to move away from SRM
