Split packages in akka.http

[atooni]

Akka HTTP Version 10.1.11:

The following packages currently occur in akka.http.core and akka.http with disjunct classes:

• akka.http.impl.settings
• akka.http.javadsl.settings
• akka.http.scaladsl.settings

We have various options here:

• Move all classes to the same package into the same artifact
• Rename one of the packages to avoid the split-package issue, preferably choosing a package name which shares the artifact name as it's prefix
• With a very good reason (is that even possible?) I think we can keep the split package, but it is the most painful and dirty solution

We are closing the issue as resolving some of the split packages in akka itself might cause binary incompatibilities. We have found another approach to handle split-packages as outlined in the README
