Change encryption logic default behaviour to not turn off encryption.
Dev ticket for https://gitlab.cern.ch/cta/operations/-/issues/372.
Make the default for new tapeservers be to enable encryption(i.e. have the respective configuration in the drive configuration default to true).
A tapeserver with encryption enabled without a script to obtain the encryption key or an invalid one should fail, and the drive should be put down. The current behavviour is to disable encryption.
