chore: do not convert ids to base64

[dyladan]

This fixes #1513

@obecny the gRPC export is still incorrect but I don't understand the gRPC/proto pipeline to understand how to fix it.

@dyladan I'm in a process of upgrading to latest proto v.0.5.0 and Im' already modifying the similar piece of code. I'm affraid they might be merging conflicts. Not sure how urgent is this fix as in fact the fix is required for next proto, and our collector exporter is not compatible with next version anyway (talking about metrics mainly, for tracing I think this is the only change), but that means that if you want to upgrade you wont be able to use metrics and traces in newest version. So upgrading might not make sense in such case, unless you only use trace.

So you're saying we should wait for the proto 0.5.0 upgrade before doing this? That's fine if that's what you want to do.

@dyladan just checked about removing conversion on top of my PR -> #1588.
Besides what you changed the missing part for grpc was to upgrade also the ids for grpc. Whatever suits you better, I can either push it to my existing PR, create a new PR to be merged to my PR, or you can add missing part of ids for grpc into your PR (I haven't yet pushed the changes to my PR)
WDYT ?

[dyladan]

Do you mean just update the ids in the tests?

[dyladan]

@obecny did you do this work in #1588?

Yes, after @vmarchaud tests it was the last thing that was still missing for proto v.0.5.0

ok then i'm closing this
