[Feature] Python Script for JSON Config Files

This PR adds a Python script capable of deploying a network function chain based on a JSON configuration. Commit log: * python cfg script working for one nf startup * adding processes for each nf * switching to threading * config.py working for 2 nf's in config * config script working for multiple params * clean up script * added documentation and example config file * switched to subprocesses for better async * working script and example json config * print statement fix * python cfg script working for one nf startup * adding processes for each nf * switching to threading * config.py working for 2 nf's in config * config script working for multiple params * clean up script * added documentation and example config file * switched to subprocesses for better async * working script and example json config * print statement fix * restoring old JSON config and fixing spacing * fixed styling errors * styling and error messages * fixes from PR review * Use 'nf->data' instead of global variables * Fix Mbps to MBps * Replace malloc by rte_malloc and remove unnecessary assignment * NFs output to log files * error statement fixes * try block for invalid JSON syntax * more print statements and extra dir function * user can now specify TTL and dir name in config file * formatting fix for documentation * flushing print statement * kill changes * fixed nf shutdown for timeout and failure * directory-prefix option * fixed formmating on config * formatting + documentation update * undo changes to tb * renaming and documentation

 The example NFs can be started using the `start_nf.sh` script. The script can run any example NF based on the first argument which is the NF name(this is based on the assumption that the name matches the NF folder and the build binary).
