Optionally avoid to fail the verify goal on bundle uninstall/update

The StaticInstallSupport does not support uninstall and update operations: in case of a refresh or bundle uninstall during resolution it fails throwing a UnsupportedOperationException. This in turn causes the verify goal of the karaf-maven-plugin to fail.

It would be nice to make StaticInstallSupport more lenient with updates and uninstall operations: a warning could be issued without failing the overall verify process.
