Summary:
`JailService` exposes jail API and knows how to
start and stop binaries. Every test should be
defined as python module with exposed
`run` method. Script `master.py` is used
for running tests and takes test module
name as argument. Machine IP addresses are
defined in environment variables. To run test
locally use `local_runner` script.
