Update maven-bundle-plugin from 3.0.1 to 3.2.0 published on 2017-01-02

We're currently using maven-bundle-plugin v3.0.1.

The latest version (http://felix.apache.org/components/bundle-plugin/) is 3.2.0 published on 2017-01-02; perhaps we'd like to upgrade to that?

The release notes on http://felix.apache.org/components/bundle-plugin/jira-report.html seem to list issues from all releases; but this https://issues.apache.org/jira/browse/FELIX/fixforversion/12335566/?selectedTab=com.atlassian.jira.jira-projects-plugin:version-summary-panel lists 3.2.0 changes - only 2 of 3 relevant for us; latest bndtool fixes (https://issues.apache.org/jira/browse/FELIX-5253) & something about better M2E integration (https://issues.apache.org/jira/browse/FELIX-4009).

FTR: The m2e-tycho mentioned in FELIX-4009 just got removed from opendaylight-eclipse-setup, due to https://bugs.eclipse.org/bugs/show_bug.cgi?id=510443.

The M2E support is something possibly of longer term interest; the latest bndtool is probably not a bad thing to move to even short term.

PS: Due to suspected issues with M2E and maven-bundle-plugin (Bug 496944), I currently use lifecycle mapping ignore for maven-bundle-plugin; that would have to be reviewed, when we upgrade, if we have a reason to use the new direct M2E integration (currently we do not really; one possible future interest could be for DS with SCR).
