http - align OTEL http attributes with latest standard

[baywet]

to maintain compatibility with external tooling we should make sure our attribute respect the latest (stable) semantic conventions. When we initially implemented things, the spec was still in draft. The following attributes need to be renamed in the middleware handlers and in the request adapter:
htttp.status_code => http.response.status_code
http.response_content_length => http.response.body.size
http.request_content_length => http.request.body.size
http.flavor => network.protocol.name
http.response_content_type => http.response.header.content-type
http.request_content_type => http.request.header.content-type
http.method => http.request.method
http.host => url.scheme
http.scheme => server.address
http.uri => url.full
http.uri_template => url.uri_template

Hey. There's a problem with this change. The kiota-http-python doesn't work with opentelemetry in version 1.23. As https://github.com/microsoft/kiota-http-python/blob/main/pyproject.toml says it should work with opentelemetry >1.20.0 that's not true.

Hi @sdarmofal
Thanks for pointing this out.
Can you open a separate issue please and expand a little on the problem you're facing?
Thanks!
