libcgroup Test: libcgroup-create-function-for-init-api

This patch creates a function test_cgroup_init() to test the libcgroup api
cgroup_init() under different scenario. In the earlier approach we were not
usong functions and were testing the api sequentialy under different conditions.
The new approach has a single function for 1 api which can handle the testing
under all conditions. The advantage is that the code repetition has reduced now.
