Documentation needed for device reconnect based on schema change

When Beryllium is started (without additional features in featuresBoot), then feature:install odl-netconf-connector-all and then feature:install another feature (for example odl-bgpcep-bgp), this is seen in karaf.log:

2016-02-09 10:41:03,007 | INFO | oupCloseable-6-1 | NetconfDevice | 182 - org.opendaylight.netconf.sal-netconf-connector - 1.3.0.SNAPSHOT | RemoteDevice

{controller-config}: Schemas change detected, reconnecting
2016-02-09 10:41:03,011 | WARN | oupCloseable-6-1 | NetconfDeviceCommunicator | 182 - org.opendaylight.netconf.sal-netconf-connector - 1.3.0.SNAPSHOT | RemoteDevice{controller-config}

: Session went down
java.io.IOException: End of input detected. Close the session.

The connection seem to re-establish successfully, but there is a brief period when controller-config device fails on any operation. This behavior is relevant for csit tests, suites should retry the operation as in this specific case failure is not an error.

There needs to be a wikipage explaining this behavior, so that test developers are informed.
