Adding wildcard feature for `DD_TRACE_HEADER_TAGS` and enabling for Http Response headers #9067

mhlidd · 2025-06-30T15:56:07Z

What Does This Do

Adds support for feature request to allow "wildcard" in DD_TRACE_HEADER_TAGS to set all headers as span tags. This PR enables this feature for only Http response headers. Modifications are made in handing the header tags to allow for the * character, and also in the handing of response headers to potentially set them as tags. Note: If the wildcard is used, all other mappings are discarded.
