Adds penalties API and display of penalties in dashboard

[rosogon]

A new REST endpoint is added to retrieve the penalties associated to an (agreement, term) pair.

The web application adds a new table in SLA tab that displays the penalties for a term (under violations table).

To test the feature, you have to add business penalties to the agreement in the last step.

Add the element BusinessValueList after ServiceLevelObjective to the availability term:

      <wsag:GuaranteeTerm wsag:Name="appAvailableSLARule___softcare-gui">
        <wsag:ServiceScope wsag:ServiceName="service">softcare-gui</wsag:ServiceScope>
        <wsag:ServiceLevelObjective>[...]
        </wsag:ServiceLevelObjective>
        <wsag:BusinessValueList>
          <wsag:CustomBusinessValue>
            <sla:Penalty type="discount" expression="35" unit="%" validity="P1D"/>
          </wsag:CustomBusinessValue>
          <wsag:CustomBusinessValue count="5" duration="P1D">
            <sla:Penalty type="service" expression="sms" validity="P1M"/>
          </wsag:CustomBusinessValue>
        </wsag:BusinessValueList>
      </wsag:GuaranteeTerm>

Once the application is deployed, you can simply stop the application (directly in CF, f.e.). Go to SLA-availability tab and check the violations and penalties there.
