The purpose of this PR is to add a nil check in the
otelhttp.NewTransport
function. I noticed this issue while I was using this library on a codebase where the transport was optionally nil. When calling Do on the wrapped client, it was throwing a nil pointer.Rather than put the onus on the user to make this check, it would be good to just transparently handle this case with a sane default (i.e. use the http.DefaultTransport).
