Add missing M2E lifecycle mappings metadata

Add missing M2E lifecycle mappings metadata

* Ignore for the duplicate-finder-maven-plugin

Not sure why I have to repeat here what I had done back in January in
https://github.com/vorburger/opendaylight-eclipse-setup/commit/abf867c9a1e58686b79214c9381adcb0e224b3b6
but I can only strongly encourage all ODL developers using Eclipse to
use the opendaylight-eclipse-setup model.

also make bundles-test-lib enable the dupe CP finder (and PMD CPD),
because that actually made the problem appear under Eclipse within
odlparent - after manually locally removing the equivalent in
lifecycle-mapping-metadata.xml by opendaylight-eclipse-setup.
