nit - I'd prefer to use HasPrefix

Frankly we could consolidate this since the only thing that differs is the name of the expected dimension.

var dimName string
if strings.HasPrefix(m.env.OS, "sles") {
  dimName = "eth0"
} else {
  dimName = "docker0"
}
dims, failed = m.DimensionFactory.GetDimensions([]dimension.Instruction{
	{
		Key:   "interface",
		Value: dimension.ExpectedDimensionValue{&dimName},
	},
	{
		Key:   "InstanceId",
		Value: dimension.UnknownDimensionValue(),
	},
})
