Simple refactoring that just simplifies some calls to `yaml_util.load_yaml` at this point.
This seems to be just fine without it (these are the only names exported here).
Removes the decision from the YamlSource call sites.

There was a problem hiding this comment.
This should be in its own load method so it can be called later.

Sorry I'm not sure how I missed this. It looks good, but it's very bare bones so I'm just assuming that the plan is to add more in future PRs. So I think it LGTM and we should move on to moving laziness into sources! |

This is the first step of #96 and @beasteers's approach to lazy source loading. (As a quick recap, that idea is to refactor laziness into the source instead of the configuration object, which is both cleaner and enables mixing-and-matching of lazy and eager sources within the same config.)
This step just consists of an innocuous but nice refactoring to use a
YamlSourceclass to encapsulate the vagaries of loading configuration data from a file. The next step would be to introduce a lazy option here: either alazyparameter to theYamlSourceconstructor or a separateLazyYamlSourceclass (or similar).
