[REPORT] Apache Karaf

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

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

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

## Activity:
  - The kloud (karaf for the cloud) initiative has been launched. The 
first goal is to improve the tooling to easily start with Karaf for both 
developers and devops.
  - Karaf Vineyard moved forward but not as fast as planned. The 
donation proposal should happen soon.
  - Karaf 4.3.x branch has started, starting to upgrade to OSGi R7 
specification and implement the "kloud initiative" features and 
improvements.

## Health report:
  - More interaction with other projects have been built. Especially, we 
are helping the jclouds community to upgrade to latest Karaf release.
  - We started an effort to have regular cadence in Karaf releases.
