- There are two different extended attributes available via the Tape REST API:
      - "user.status" : Provides information about file locality in the storage system (if it is on tape, disk or both)
      - "taperestapi.version" : Tells which version of the Tape REST API is the endpoint running (gfal only supports endpoints in "v1"

  - Introduces TestCaseBase(..) as a base class for all the tests
  - Starts functional tests for bring online operations
  - Implements a GfalWrapper(..) class that extends some functionalities of the gfal2 python bindings
