Add OSGified version of akka-pki

[rovarga]

Describe the bug
akka-2.6.6 has introduced a new jar, akka-pki, which does not have an OSGi manifest. This jar is used by akka-remote, which refers to versioned imports of packages contained therein.

To Reproduce
Steps to reproduce the behavior:

1. Attempt to load akka-remote with osgified dependencies
2. See error :)

Expected behavior
akka-remote should resolve its imports from akka-pki.

Environment

• JDK 11.0.7
• Scala 2.13.2
• Akka 2.6.6
• Bundle akka-remote, requiring akka-pki
• Karaf 4.2.9 (OSGi R6)
• Unable to resolve com.typesafe.akka.remote/2.6.6: missing requirement [com.typesafe.akka.remote/2.6.6] osgi.wiring.package; filter:="(&(osgi.wiring.package=akka.pki.pem)(version>=2.6.0)(!(version>=2.7.0)))"

Hi, We are also affected by this broken osgi in typesafe. Looks like this thread is open for long. Any updates or closure expected in neartime?

Hello, at the moment we are not working actively on the project that is using OSGi, so the OSGi support is unlikely to evolve from our side. This having said, we are evaluating a new architecture outside of OSGi and Akka - looking to have a more FP oriented foundation for the next version of our framework.

I am afraid the Akka OSGi support is just dying out.

FWIW, we have opted to have an uber-bundle of what we need of Akka+OSGi for OpenDaylight -- it is available on Central here: https://search.maven.org/artifact/org.opendaylight.controller/repackaged-akka/ .
Alternatively, you can brew your own -- our approach at doing that can be found here: https://github.com/opendaylight/controller/tree/master/akka
