Feature Request: opentelemetry-instrumentation-urllib3 add support for custom span names via callback

[ZachTB123]

opentelemetry-instrumentation-urllib3 always uses a default span name here. It would be nice if a custom name callback was supported like opentelemetry-instrumentation-requests does here.

hi, can you assign this to me? thanks :)

@avzis
We are actually getting rid of span name callbacks in favor of request/response hooks. PTAL at #411 and implement it using hooks instead of callbacks if you are still interested in working on this.

@lzchen PR #576 implements it using hooks. Is there additional work to add on top of these changes?

I believe this is no longer required.
