Code Issues Proposed changes

Move task_log functions to conductor

Browse Source 
This moves the use of the following functions in compute/utils to
the conductor:

  task_log_get()
  task_log_begin_task()
  task_log_end_task()

This removes the db import from compute/utils.py

Related to blueprint no-db-compute
