odl-sfc refactor:Include sfc and utils library
- JIRA:SFC-54 - This has not yet taken care of pre-steps in exec_tests.sh - Commonly used functions moved to utils.py - Improvise Threading for capture_time_log using join and timeout - Add get_compute_nodes function and improvise on create_instance for multiple compute node use cases Change-Id: Ia05fea161b191bd548a3010d7e5ef02fcf69da20 Signed-off-by: Vijayendra Radhakrishna <vradhakrishna@mvista.com>
