Implement the handling of PM
Implement the RPC "pm-interact" (CRUD) in order to handle PMs and also implement "PmDescriptions" which is a description of the PMBehavior (max/min values, etc...).
Each time a CurrentPm is modified in the operational DataStore, the new Pm measurements will be examined. If a value is out of the bundaries defined by PmDescriptions then the port associated to the Pm will become outOfService.
