Adding support for externally passed random seed and printing used seed on
console
It's good practice to execute tests in random order. That ensures tests are
atomic and not depend on each other or some stateful entity. But, if such error
occurs, right now, there is no way to reproduce this exact, erroneous execution.
This PR adds the ability to reproduce those errors by adding support for
externally passed random seed. If random seed is not passed, it will be
generated automatically. Also, random seed will be printed on console. That's
enable it to be achieved by CI server for later.
This operation is strongly influenced by Ruby's rspec order command line
