Add Span decorators to Processors. Name suggestions?

[tsloughter]

Per the spec we can have Span "decorators" do modify the Span in the built-in processors. This still needs to be added.

They could be used for things like adding baggage to the Span attributes instead of using a separate Span Processor.

I don't like the name "decorator" for these in Erlang/Elixir since people equate those with decorating a function, so name suggestions would be helpful.

Is this still valid? I don't find anything about "Span decorators" in the spec?

[tsloughter]

Ah no, it isn't. The decorators were removed from the spec: open-telemetry/opentelemetry-specification#3363

So I'll close this.
