OpenStack instance benchmarking framework (inspired by ServerBear benchmarking)

Supported benchmark suits:

• UnixBench
• fio
• Iperf

1. Create an OpenStack instance and run install.sh on it. This will install the ursus server (used to collect benchmarking results)
2. Run start_benchmark.py (start_benchmark.py -h to see available options)
3. Wait for benchmarking to finish, then check /var/www/ursus/ursus.db SQLite database to see the results
