[SCLabelPolicy] Labels aren't updated on existing policies when using Labels property

[ykuijs]

Details of the scenario you tried and the problem that is occurring

When you want to update an existing label policy, the resource doesn't do anything when using the Labels property. This is because the Labels parameter is removed in the code, since the Set-LabelPolicy cmdlet doesn't support the Labels parameter.

Suggested solution to the issue

We need to change the code to populate the AddLabels/RemoveLabels, based on the labels specified in Labels and the actually applied labels

Working on it.

Also updated the code to check if Labels and AddLabels/RemoveLabels are provided. These can't be used simultaneously.
