otel-collector processors list is using map keys, which is sorted alphabethically.
Some processoers should be used in order i.e. tail_sampling before batch, so this PR adds additional property to set proper order of the processors. It can only be used together with processors definition.
Change is backward compatible

Should processors and processorOrderedList be mutually exclusive? Curious why we shouldn't deprecate processors or simply change its shape as processors is effectively buggy it seems

doesn't this mean without processors, processorOrderedList does not work?
