Restart level calculation in SimpleResourceDefinition.Parameters is ineffective.

Parameters attempts to set a restart level for add or remove based on the type of the handler for the op:

    public Parameters setAddHandler(OperationStepHandler addHandler) {
            this.addHandler = addHandler;
            if (this.addRestartLevel == null) {
                this.addRestartLevel = restartLevelForAdd(addHandler);
            }
            return this;
        }

The problem is restartLevelForAdd(addHandler) doesn't get called because this.addRestartLevel and this.removeRestartLevel are initialized to non-null values.

The effect of this is SimpleResourceDefinition impls that moved from passing multiple params to the constructor to instead passing a Parameters object have had the restart-level description of their add and remove ops changed.

This is tricky because fixing this means some things may get changed back.
