* Add url to traces

* Remove opentracing

* Remove gopkg.* files

* Start deprecating opentracing

* Resolve stupid build errors

* Use observability package

* Fix test errors

* Convert buffalo spans to observercontext

* change package name

* defer flush to the end of the app execution

* Change op names to the correct package

* Rename pkg/observability to pkg/observ

* Show traces for the package

* Keep tracing in the earlier way

* Add info from request headers

* Remove whitespace

* Move exporter url to env var

* Add to env file for documentation

* Remove opentracing stuff

* Use stdlib
