This method implements the default activation policy for components
It thus follows this algorithm:
- Obtain first the node's 5 most suitable replicas
- If replica number is less than 2, it is impossible to activate new components (node is isolated)
- Identify which node is overwhelming this component, and activate new object replica there, unless there is an
already active instance within that node.
Factory method used for creating an inner object within a component
Useful for components which may delegate some view implementations to other classes / objects
