// newAggregate is a modified copy of k8s.io/apimachinery/pkg/util/errors.NewAggregate.
// NewAggregate converts a slice of errors into an Aggregate interface, which
// is itself an implementation of the error interface.  If the slice is empty,
// this returns nil.
// It will check if any of the element of input error list is nil, to avoid
// nil pointer panic when call Error().
