Updating the topology should only change the operational state of the services

Currently, whenever the topology is updated, we update path descriptions and services status accordingly. For example, a node from the topology that becomes "outOfService" will trigger the update of all path descriptions and services that may be using the node in question. If a service appears to contain this node in its path description, it will become "outOfService" accordingly.

However, in the process of changing the state of services, we indistinctly set the OperationalState and AdminState attributes with the new state ("outOfService" for example). Typically, only the value of OperationalState needs to be modified.

Acceptance criteria : the code does not bring regression, associated Junit tests are provided
