Arguments:
- test: the ReFrame test to which this hook should apply

The following test attributes must be set:
- compute_unit: a device as listed in eessi.testsuite.constants.COMPUTE_UNITS
- num_tasks_per_compute_unit: the number of tasks per compute unit

Examples:
On a single node with 2 sockets, 64 cores and 128 hyperthreads:
- assign_tasks_per_compute_unit(test, COMPUTE_UNITS.HWTHREAD) will launch 128 tasks with 1 thread per task
- assign_tasks_per_compute_unit(test, COMPUTE_UNITS.CPU) will launch 64 tasks with 2 threads per task
- assign_tasks_per_compute_unit(test, COMPUTE_UNITS.CPU_SOCKET) will launch 2 tasks with 64 threads per task
- test.compute_unit = COMPUTE_UNITS.HWTHREAD will launch 128 tasks with 1 thread per task
- test.compute_unit = COMPUTE_UNITS.CPU will launch 64 tasks with 2 threads per task
- test.compute_unit = COMPUTE_UNITS.CPU_SOCKET will launch 2 tasks with 64 threads per task
