[migration] Completed #644:

- Added tool to drop from the CTA catalogue all CASTOR tapes from a given tapepool.
  This tool makes use of a temporary table and an additional PL/SQL procedure
  in order to perform efficient bulk operations in the CTA catalogue.
- Made tapepool insertion idempotent.
- Updated documentation.
