Remove dependency on akka in the rdf module #4059
Description
- Chose the right version of http4s for our version of Scala / cats-effect
- Import it and make sure it does not create any classpath clashes (limit to
http4s-core) for now - Migrate to the Uri implementation from the one in akka to the one available in http4s
- Create utility method to move from one to another if needed
- Move up things related to akka not used directly in the rdf module to the sdk
