MasterSlave* classes were deleted

Classes were removed for the following reasons:

1) They doesn't bring any significant value. Especially for complex
    apps where the are supposed to be used
2) The naming is not appropriate
3) There are no appropriate names exist because those classes can
   be equally good used for scenarios where there is a primary/secondary
   nodes, when there are 2 types of nodes with different relations or
   even for just 2-components apps
4) Thus property names like master and slave limit inheritors in
   giving them better names that better reflect component roles
   within the application
