Method getDiskResource

src/tests/persistent_volume_tests.cpp:213–253

Creates a disk with / without a `source` based on the parameterization of the test. `id` influences the `root` if one is specified so that we can create multiple disks in the tests.

  // parameterization of the test. `id` influences the `root` if one
