Fix issue with multiline comment in OSGI properties

If a component property as a multiline comment the app activation
will throw an exception and no property for that component would be initialized.

This patch address that in two ways:
- Make sure that if we cannot parse a line from cfgdef the other properties are enabled and logs a warn.
- Changes the onos-maven-plugin so that it removes new lines when generating the .cfgdef file

Bumping version as plugin is already published from onos-2.5 branch
