glusterd, cli: Task id's for async tasks
This patch introduces task-id's for async tasks like rebalance, remove-brick and replace-brick. An id is generated for each task when it is started and displayed to the user in cli output. The status of running tasks is also included in the output of "volume status" along with its id, so that a user can easily track the progress of an async task. Also, * added tests for this feature into the regression test suite. * added a python script for creating files, 'create-files.py', courtesy Vijaykumar Koppad (vkoppad@redhat.com) into the test suite. This patch reverts the revert commit 698deb33d731df6de84da8ae8ee4045e1543a168.
