Support more encodings for Kafka in OTel Ingester

[XSAM]

Resolves #2579

[joe-elliott]

I don't mind merging this PR (particularly if it allows @XSAM to do something interesting with the Jaeger OTel Ingester), but all of this functionality is still being discussed and this may change in the final version.

So I generally expect this to change, but don't think there's any issue adding this flexibility to the OTel components for now.

@XSAM looks like you need to sign some commits? Other than that LGTM

Are there any documentation changes required to accompany this?

Given that this is all likely to change and none of this is documented I think this is fine. I tried to make it clear that this is all currently up for debate and may change. I think @XSAM is just experimenting with the Otel pieces and this was something they needed.
