This provides the Chart.yaml field `tillerVersion`, which is a semver range. It allows users to choose to constrain a chart to a specific version. The reason for this is that we keep introducing new template functions, but we have no way of saying "this chart will only work with Tiller newer than...". The check on version is _only_ done on Tiller. The client does not check at all, since it does not do any template expansion on its own.
