👋 From the serverless team - I'll test this in a couple runtimes/environments to double-check that there aren't any duplicate/missing tags in traces and profiles anywhere and report back! Thank you for doing this! |

Do we want to filter here if tags are empty ? I assume this would be filtered either way afterwards by Tag::new(name, value).ok()

Looks good to me.
NIT: Tests could include more invalid characters / empty tags to check behaviour on edge cases.

This gives Azure Functions a span attribute extension_version: unknown which should only apply to Azure App Services
Span with this change:
Span without this change:
It turns out I can't test dev versions of libdatadog in dd-trace-dotnet, which is what Azure App Services Windows uses for profiling 😅, but looking at the code I also don't think AAS is supposed to get those functions runtime tags. AFAIK the DD_AAS_DOTNET_EXTENSION_VERSION env only gets set by the AAS extension in .NET and similarly the runtime env vars only get set in Azure Functions
So these environment variables are supposed to be mutually exclusive, and this would cause tags with unknown values to be added to environments where those env vars don't exist.
libdatadog is used in Azure Functions for traces, but not profiles, so this affects traces in Azure Functions
libdatadog is used in .NET AAS Windows for profiles, but not traces, so this affects profiles in AAS Windows
cc @duncanpharvey, correct me if I'm wrong!

What does this PR do?
Unifies the azure tags used by profiling and tracing
Motivation
The tags had diverged, we should have one source of truth.
Additional Notes
Profiling only:
aas.environment.extension_version
Tracing only:
