  CASTOR-5350: Introduce encryption SCSI commands in tape drive
  backend

  Implementation of two methods:
    * setEncryptionKey(key): Sets encryption params to drive.
    * clearEncryptionKey: Clears encryption params from drive.

3cf91d48f5c7b0cb563c3037aee69ec769f5ab94
  Added support for an interface script that will setup drive
  encryption per tape

  CASTOR-5350: Encryption backend

  ## Description
    The aim of this merge request is to incorporate encryption support
    into CASTOR.
    The proposed changes are to be used in conjunction with the
    operators'
    [ExternalEncryptionKeyScript](https://gitlab.cern.ch/slaskari/castor-get-encryption-key).

    The **aim** is to enable encryption in specific tape pools of
    CASTOR.
  ## Changes
    * Introduce encryption SCSI backend to DriveGeneric.
    * Introduce encryption control wrapper
    * (`castor/tape/tapeserver/daemon/EncryptionControl`) for
    * abstracting the two sub-components of:
      * Calling the `ExternalEncryptionKeyScript`,
      * Calling the equivalent DriveGeneric function for
      * passing/clearing the encryption parameters to/from the drive.
    * Add new configuration option in `castor.conf` for the external key
    * management script.
    * Create a Subprocess wrapper for executing external commands as
    * CASTOR children (`castor/server/Subprocess.{h,c}pp`).
    * Incorporate encryption handling in the:
      * DataTransferSession
      * LabelSession
      * CleanerSession
    * Add encryption control timer in the task Watchdog.

  Clear encryption key only when encryption enabled
  Changes include:
    - Making EncryptionControl stateful
    - Calling clearEncryptionKey on the drive only when encryption is
      on.
  Also includes a minor duplicate code fix on DriveGeneric.

  Merge branch 'encryption_changes' into 'master'
  Clear encryption key only when encryption enabled
  ## Description
    Changes include:
    - Making EncryptionControl stateful
    - Calling `clearEncryptionKey()` on the drive only when encryption
      is on.
    Also includes a minor duplicate code fix on **DriveGeneric.cpp**.

  Check if the drive has encryption capability enabled:
    * Add isEncryptionCapEnabled() vendor-specific function
    * Check isEncryptionCapEnabled() before passing encryption params
    * Check isEncryptionCapEnabled() before clearing encryption params
    * Clear encryption key before unencrypted I/O

  Merge branch 'encryption_capability_enabled' into 'master'
  Drive encryption capabilities inclusion
  ## Description
    The aim of this merge request is to address issues related to
    encryption on drive without the encryption capability enabled.
    More specifically:
      * It introduces a vendor-specific way of identifying if the drive
      * has encryption capability enabled
      * **IBM**: Through the SPIN index SCSI page
      * **Oracle**: Through the general INQUIRY SCSI page
      * If the data to be written are to be encrypted, an additional check
      * of the encryption capability of the drive is made. In case of
      * encrypted data, but no encryption capability, the session fails.
      In essence, all encryption related operations are made modulo the
    encryption capability of the drive.
      Last, in case of unencrypted I/O, we clear the keys of the drive (if
    encryption capable) to avoid encrypted data with previous keys on
    CASTOR's system failure.
  ## Testing
    Before the merge request's submission, the following tests were
    passed:
      On drives with **encryption capability enabled**:
        * Label session
        * Label with previously set encryption key
        * Write without encryption
        * Read without encryption
        * Write with encryption
        * Read with encryption
        * Write with previously set encryption key
        * Read with previously set encryption key
      On drive with **encryption cabability disabled**:
        * Label session
        * Write without encryption
        * Read without encryption
        * Write with encryption - session **should** fail
        * Read with encryption - session **should** fail

This implied removing tpconfig, tplabel and tpstat.

Introduced the scheduler to the DataTransferSession, replacing the concept of DGN with logical library

Please note that you will have to install the following CASTOR rpms
in order to compile:

  castor
  castor-devel
  castor-lib
  castor-lib-server
  castor-lib-tape

Renamed CTA/tapeserver/castor to CTA/tapeserver/castor_checkout in preparation for the moving the sub-directory CTA/tapeserver/castor/castor up the directory tree

Fixed.

Removed "h/" from all #includes.

CASTOR-4772 The code to parse the name of a slot in a tape library should be implemented in one place

Added TapeLibraryType and TapeLibrarySlot.

The C++ namespace castor::tape::tapeserver::drive now matches its
directory structure.
