Add workers package

Package workers is responsible for Workers list management. Moreover
it implements Superviser and Workers interfaces. It can be used either
directly from API handlers or indirectly through a decorator which can
add authentication layer. It can also be aggregated with implementation
of Requests interface to construct a implementation of Server.
Tests are added in order to achieve 100% coverage.
