New 'balloons' policy, bugfixes, dependency updates.

This release introduces the new balloons policy. It also adds support for namespace-based allocation of reserved CPUs as well as pod- and namespace-based colocation of containers to the topology-aware policy. In addition to these, the release contains various other smaller functional improvements and a number of bug fixes. Dependencies are updated to more recent versions.
