[REPORT] Apache Karaf

[Jean-Baptiste Onofré <jb...@nanthrax.net>]

## Description:
 - Apache Karaf provides a modern and polymorphic applications runtime,
multi-purpose (microservices, OSGi, etc).

## Issues:
 - There are no issues requiring board attention at this time

## Activity:
 - Once Karaf 4.2.2 will be released, master will become Karaf 4.3.x,
upgrading to OSGi R7.
 - We are working on two new PoC for Karaf:
   * Karaf Vineyard is a API management platform powered by Karaf,
providing API registry and gateway
   * Karaf Winegrower is the new karaf boot name. The purpose is to
provide a complete framework/tool allowing developers to start very
easily with the Karaf ecosystem
 - We also start discussion about improving the Karaf features service
to better leverage resources repositories.

## Health report:
 - We can see interaction with different community (jclouds, OpenNMS,
...) and a general activity increase especially from users community
 - We also agree to define a cadence in Karaf runtime and subprojects
release cycle (every 3 months). It allows to include fixes/jira update
most often in release and gives a better roadmap to our users.
