Add requireAllDemandsAndIgnoreOthers flag

[Nohac]

This PR adds an extra option requireAllDemandsAndIgnoreOthers (name tbd) to the azure pipeline scaler which ensures that all demands in the scaler definition is present in the incoming job, while ignoring any other demands the job may have.

This is different from requireAllDemands which requires all demands to be an exact match.
