tests: Add functional test for basic cgget operations

This commit adds a functional test for a basic cgget call.  The
test utilizes the new functional text framework and lxc
containers to establish a non-destructive cgroup test
environment.

Tests added:
    001-cgget-basic_cgget.py - Test simple cgget functionality
