Deploy the bundle via the dedicated DAV url

[kwin]

For reasons like outlined in adobe/aem-project-archetype#56 and https://issues.apache.org/jira/browse/SLING-7916 the following plugin configuration should be used for the sling-maven-plugin:

<plugin>
  <groupId>org.apache.sling</groupId>
  <artifactId>maven-sling-plugin</artifactId>
  <configuration
    <slingUrl>http://${crx.host}:${crx.port}${crx.contextRoot}/crx/repository/crx.default</slingUrl>
    <slingUrlSuffix>/apps/acs-commons/install</slingUrlSuffix>
    <deploymentMethod>WebDAV</deploymentMethod>
  </configuration>
</plugin>

That way this works in almost all existing AEM installation (no matter how they are configured).
