Missing the Attributors Processor

[matheuscanela]

Tried to use attribute processor and it doesn't seem to be compatible with Lambda/Node JS layer.

I tested the two configuration files below, but they didn't work. Is it possible to add to Lambda layer?

@wangzlei I think we should add all the processors except for batchprocessor from core

https://github.com/open-telemetry/opentelemetry-collector/tree/main/processor

They seem like they should have a very small effect on binary size. The most important though are attributes, memorylimiter, resource, span processors.

Thanks @anuraaga
They are really important as customers would like to remove PII data, which is not possible without the processor - am I right?

[wangzlei]

@anuraaga How about let users pick up what components they want, even batchProcessor if they take the data delay/lost risk, by #100 ?

[anuraaga]

@wangzlei Making it easy to build a custom collector, especially to choose backends, is important I think, but for core features like processors, which also shouldn't add any significant binary size at all, we should just include them by default.
