PR #8118 - adding to_dict to the dependency manager and an embedded loading of dependency resolution options from galaxy.yml - was really quite poorly thought through.
Certain options could be embedded - but only the resolvers and the actual dictified representation of the DependencyManager couldn't be actually embedded properly in the app config - but this is exactly what I wanted to do on the Pulsar side and it would make no sense to have the exact same options in both apps and configured differently.
So now the actual dictified representation of the whole DependencyManager can be directly embedded in galaxy.yml as the ``dependency_resolution:`` parameter. All the parameters can still be configured at the top level of the YAML file but with 'dependency' in the config option name (some prefixes, some suffixes, etc... a hodgepodge that has grown organically). Give the messiness of the existing options might be better to encourage using ``dependency_resolution:`` in the future.
