Description

Background:

Parsing the value "NULL" for a configuration node currently throws. This is potentially an issue with yaml-cpp: https://github.com/jbeder/yaml-cpp/issues/590. The fix is ready on their side, but as of the creation time of this Jira, it is yet to be released (last version known not to have this fix: yaml-cpp-0.6.3).

Proposal:

Once the new release of yaml-cpp is out, we should upgrade our dependency as well. On upgrading please check the changelog for potential behaviour changes.
