This implementation splits the execution and node configuration
components of the conf.yaml into two separate config files. A
new command line argument is added, allowing the user to specify
both a node configuration file and an execution configuration
file. Be default, these config files are now named node_conf.yaml and
execution_conf.yaml, respectively.
To assert these changes, the schema calls for one of these objects,
nodes or executions, in each file, but neither config file can have
both.
To avoid excess refactoring, both config files are merged together
early on in the load_config process.

There is an alternative approach to this that I currently have
implemented on a separate local branch. Essentially, both configs are
merged together before being validated by the schema, effectively
removing the need to change the schema at all as well as the above
assertion that both nodes and executions are in the two config files.
However, using this alternative method might mean that is no added
control that prevents users from making funky errors when creating
both config files. I could also just be overthinking or missing
something.
